F1 Advanced Firewall supports 250 authenticated users as standard, expandable to 5000 users with the addition of user license packs.
F2 Static Network Address Translation (SNAT) (Source Mapping) is an integral component of Advanced Firewall.
F3 Outbound (egress) traffic control (user access to Internet services) is an integral component of Advanced Firewall
F4 Support for multiple public aliased IP address is a standard feature of Advanced Firewall.
F5 For load balancing, where for example high traffic applications are served by multiple web servers responding to page requests from a single public IP address.
F6 Egress Filtering incorporates traffic inspection technology to detect and block Peer to Peer (P2P) traffic such as KaZaA, Bit Torrent and eDonkey, regardless of which port the file sharing software attempts to use.
F7 Internal firewall segregation of local networks into physically independent zones. Inter zone access (bridging) controlled by user authentication (eg only system administrators allowed admin access to DMZ servers)
N1 Advanced firewall will support 4 NICs as standard, license expandable to 20 NICs and VLAN trunk (802.1Q) interfaces by license.
N2 Smoothwall Express supports a single active External Network (Internet) connection. Smoothwall Express supports a single External Internet (Red) interface, a DMZ (Orange) and a Local Protected Network (Green). Advanced Firewall can support multiple active External Network connections as any NIC can be designated as External (Red), Local Protected (Green) or DMZ (Orange).
N3 Multiple internal network zones allow the physical separation of different user groups, internal servers, publicly accessible servers etc. Inter-zone access rules permit strictly limited access from one zone to another (by server/IP address, port/service etc.).
N4 Advanced Firewall and Smoothwall Express can all support a single active PPP (dial-up) connection (eg ISDN, ADSL modem or analog modem). Multiple connection profiles (eg ISP details) can be stored.
N5 Outgoing traffic can be load balanced between multiple external network interfaces, with a weighting facility to control the proportion of the total traffic being routed via each interface in the load balancing pool. Both NAT and web proxy traffic can independently be subject to load balancing. Specific IP addresses, such as mail-servers can be excluded from being load balanced. Alternatively, traffic can be split between multiple external (Red) network interfaces according to the IP address, IP address range or network address of the originating computer. Traffic may also be split according to port (protocol) in order to separate web and email traffic, for example.
N6 If an Internet connection should fail then Advanced Firewall can be configured to automatically route all traffic from the failed interface to another. There is no limit to how many interfaces can be set in the failure cascade path, nor is there any limitation on the type of interface that can be used (Ethernet, ADSL modem, ISDN or analog modem).
N7 802.1Q VLAN trunking support allowing communication with VLAN capable switches and the routing of traffic between VLANs.
N8 For easier support of cable modems which will typically only communicate with the MAC address from which the modem or Internet connection was initially configured.
N9 Advanced Firewall can be used in an Active/Passive High Availability (HA) configuration with fully automatic failover should one appliance fail.
N10 Inbound traffic may be load-balanced over two or more Internet connections for increased bandwidth availability and resilience (in the event of an Internet connection failure).
Proxies and Application Helpers:
P1 Squid caching web proxy server (reduces page display times and Internet bandwidth utilization).
P2 Configuration options include: cache size, max object size, logging options and domains not to be cached.
P3 Reconstructs and relays incoming email to a protected mail server located within a local network zone or DMZ, with support for an unlimited number of domains. Transparent relay of outgoing SMTP email.
P4 The transparent POP3 proxy provided by the SmoothZap module for Advanced Firewall ensures that all POP3 email, whether company or personal email, is subject to anti-virus and anti-spam controls without any configuration changes to users’ email client software. Express includes a POP3 proxy for anti-virus purposes only.
P5 SIP registering proxy for inbound connections to SIP phones and softphones (PC clients).
P6 Transparent SIP proxy and gateway for the protection of VoIP telephone systems, supporting the use of a remote SIP proxy at an Internet Telephone Service Provider (ITSP).
See the Hardware Compatibility Guide: http://www.smoothwall.net/support/hcg for full information on the hardware supported by Smoothwall Security Software.
H1 Supported RAID controllers will Include Compaq, Dell PERC and DAC960.
H2 Software RAID Software RAID 1 (Mirroring) using two IDE, SATA or SCSI disks which do not have to be of identical size. The firewall will remain operational in the event of a single disk failure. Automatic mirror rebuild.
H3 SCSI controllers from Adaptec, Future Domain, Sym Bios, Initio, Advansys and BusLogic are supported.
H4 Smoothwall Express supports a limited set of SATA disk controllers. Advanced Firewall supports all common SATA controllers.
H5 Gigabit Ethernet cards from Intel, 3Com, Broadcom and other manufacturers.
H6 Multi-Port NIC support includes Intel quad and dual port cards, 3Com dual port cards and the DLink DE580 4 port card.
H7 Over 30 types of USB ADSL modems are supported, along with Ethernet connected ADSL modems and the BeWAN PCI ADSL card modem.
H8 Drivers for numerous PCI ISDN cards are included, together with support for USB ISDN and RS232 connected ISDN Terminal Adapters.
H9 Hayes compatible RS232 connected analog modems and several ISA card modems are supported.
H10 Compact Flash can be used as an alternative to hard disk for appliance applications. Advanced Firewall includes logic to operate with reduced space relative to hard disk operation, a minimum flash memory capacity is 256 MByte with 512 MByte recommended. The flash memory must present itself as an IDE device. Express can also operate on flash memory but does not include the extra logic to reduce space requirements. Logs will be stored in a non-persistent (volatile) RAM disk, thus the use of Syslog for off-box log recording is recommended.
H11 BeWAN PCI ADSL modem.
H12 Supports APC models. Advanced Firewall can support UPS slave mode operation, where up to 5 systems (eg Advanced Firewall, Unix/Microsoft Windows system running apcupsd software) on the network can share the same UPS.
Installation / Maintenance:
IN1 Advanced mode installation provides full set of Setup configuration options whereas Basic mode installation applies sensible default values to reduce the number of configuration questions presented during installation.
IN2 Smoothwall Security Solutions are based on a cut-down security hardened version of the Linux operating system, where all unnecessary components have been removed from the operating system, reducing disk and memory utilization, improving security and performance.
IN3 Security updates and bug fixes are supplied free of charge for all supported Smoothwall products.
IN4 To be able to select which rules/configuration information to restore from a Smoothwall Configuration Backup (allowing specific rules, such as Port Forward rules, to be copied between systems).
IN5 Option to automatically download and store any new updates on the firewall, which can then be applied at a convenient time by administrator command.
IN6 All updates (patches) present on an installation CD will automatically be applied.
IN7 Any modules present on the same CD as the firewall software will be automatically installed (single disk installation).
IN8 MAC address of each Network Interface Card (NIC) displayed. Network cable status (present/not present) displayed to help identify a particular NIC when multiple NICs of the same type are installed.
IN9 Smoothwall and its authorized Resellers can supply pre-installed versions of Advanced Firewall, providing pre-configured installations.
C1 Configurable home (Control) page options allow the display a variety of information, including alert messages, system status, VPN status, traffic statistics, firewall reports, update/blocklist status and various information from the SmoothGuardian web filtering add-on module.
C2 All rule lists and log files can be sorted on any column (eg IP address, source port etc.).
C3 Master to slave configuration replication can be to automatically propagate configuration changes from say a head office system to remote branch office systems.
A1 Integrated Kerberos user authentication system to work with LDAP authentication systems such as Microsoft Windows 2000® and Microsoft Windows 2003® Server using Active Directory.
A2 Support for the common InetOrgPerson (RFC2798) schema.
A3 With Advanced Firewall, this authentication database can also be used to control users’ access to Internet services (outbound/egress rules) and inter-zone access.
A4 An Ident client for Microsoft Windows™ operating systems can be used to identify the computer user to the Smoothwall system.
A5 The SSL Login page automatically senses from the users’ browsers if it should display in English, German, Italian, Spanish, Danish, Dutch, French or Swedish.
A6 Multiple internal network zones allow the physical separation of different user groups, internal servers, publicly accessible servers etc. Inter-zone access rules permit strictly limited access from one zone to another (by server/IP address, port/service etc.). User authentication can be used to control which access control policies (rule-sets) are applied to a user session.
A7 Access for VPN users to internal servers and services can be controlled by user authentication, ie determines the policies (rule-sets) are applied to that VPN session.
A8 Multiple users with configurable access rights (eg reporting only, network configuration etc.)
Intrusion Detection:
IDS1 Email and SMS text message alerting is an integrated into Smoothwall’s commercial software. Alerts are generated based on intelligent monitoring of hardware, user and network activity, whilst reports are scheduled for regular delivery.
Virtual Private Networking (VPN):
V1 X509 certificate authentication is recommended or Pre-Shared Key (PSK)/Shared Secret authentication can be used. Smoothwall Express supports site-to-site VPN tunnels using Pre-Shared Key (PSK)/Shared Secret authentication.
V2 IPSec VPN connectivity for single computers (mobile/laptop/home user/Road Warrior users) is an integral component of Advanced Firewall.
V3 Layer 2 Tunneling Protocol (L2TP) VPN connectivity for single computers (mobile/laptop/home user/Road Warrior users) is an integral component of Advanced Firewall.
V4 Advanced Firewall supports 20 VPN tunnels as standard (any combination of IPSec site-to-site, IPSec Road Warrior or L2TP Road Warrior tunnels). This can be expanded to a maximum of 500 tunnels by the addition of VPN license packs. The lack of individual tunnel management facilities in Smoothwall Express makes it impractical to establish and control more than a few VPN tunnels.
V5 Advanced Firewall includes a Certificate Authority (CA) for the creation and issue of self-signed x509 certificates. Alternatively an external Certificate Authority, such as Microsoft Windows 2000/2003 Server may be used, or an external certificate provider such as Verisign or Thawte.
V6 NAT Traversal (NAT-T) mode for IPSec VPN connections is supported as standard.
V7 Either L2TP or IPSec VPN can be used for local as well as remote (Internet) VPN connections with Advanced Firewall. This is principally used for Wireless (WiFi) access, providing secure L2TP connections with the user PC authenticated using an x509 certificate and the data encrypted using the 3DES encryption algorithm. IPSec internal subnet routing can also be configured.
V8 The Firewall will log each connection and disconnection by mobile/laptop/home user/Road Warrior VPN users, with option to display an alert message on the GUI Home (Control) page or send Alert message by email or SMS text message.
Logging and Reporting:
L1 To reduce disk space utilization for non hard-disk operation (eg flash memory).
L2 All log files and rule lists can be sorted on any column (eg IP address, port, time etc.)
L3 Advanced Firewall includes scheduled reporting, which is available for most reports and integrates with all add-on modules.
L4 Advanced Firewall provides more detailed traffic statistics than Smoothwall Express, with the option to generate an alert message reports if the current inbound or outbound traffic exceeds a configurable threshold. There is also a volume threshold where an alert can be generated if the total traffic volume exceeds a configurable limit for a daily/weekly/monthly limit.
L5 Query an Advanced Firewall system to report management information, including disk utilization and traffic information.
M1 Modularization of many components/services, such as the DHCP server and the Web Proxy, allows them to be removed as desired. This allows the system to be customized and the memory/system requirements reduced if desired. The required modules can be configured at install time, thus the system can be tailored to the target hardware.
M2 The ClamAV anti-virus engine supports the SmoothGuardian (web security/content filtering) and SmoothZap (email security/anti-spam) modules. Automatic updates to virus signatures.
System Requirements:
S1 For Advanced Firewall the minimum recommended processor is a Pentium III 500 MHz (2 GHz+ recommended). Compatible processors from AMD and VIA are supported.
S2 For Advanced Firewall the minimum recommended memory is 128 Mbytes DDR or similar fast RAM. For Smoothwall Express minimum memory is 64 Mbytes with 96 Mbytes recommended. For Advanced Firewall the maximum useable memory is 4 GBytes; for Smoothwall Express the maximum useable memory is 950 MBytes. More RAM memory is beneficial for web proxy cache performance and is necessary for operation of the SmoothGuardian web content filtering module.
S3 For Advanced Firewall the minimum recommended hard disk capacity is 4 GBytes. Alternatively Advanced Firewall can utilize compact flash memory instead of a hard disk, when 256 Mbytes flash memory is the minimum recommended figure. The compact flash must appear as an IDE device, with logging to non-persistent (volatile) RAM disk.
