ProSafe VPN Firewall 200 FVX538 Reference Manual Table 4-2. Outbound Rules (continued) Item Bandwidth Profile Log Description Bandwidth Limiting determines the way in which the data is sent to/from your host. The purpose of bandwidth limiting is to provide a solution for limiting the outgoing/ incoming traffic, thus preventing the LAN users for consuming all the bandwidth of our internet link. Bandwidth Limiting for outbound traffic will be done on the available WAN interface in the single port and Auto-Failover modes. The limiting will be done on the user-specified interface in Load Balancing mode. The bandwidth limiting for inbound traffic will be done on the LAN interface for all WAN modes. Bandwidth Limiting will not apply to the DMZ interface. This determines whether packets covered by this rule are logged. Select the desired action: • Always - always log traffic considered by this rule, whether it matches or not. This is useful when debugging your rules. • Never - never log traffic considered by this rule, whether it matches or not. Inbound Rules (Port Forwarding) Because the FVX538 uses Network Address Translation (NAT), your network presents only one IP address to the Internet and outside users cannot directly address any of your local computers. However, by defining an inbound rule you can make a local server (for example, a Web server or game server) visible and available to the Internet. The rule tells the firewall to direct inbound traffic for a particular service to one local server based on the destination port number. This is also known as port forwarding. Whether or not DHCP is enabled, how the PCs will access the server's LAN address impacts the Inbound Rules. For example: • If your external IP address is assigned dynamically by your ISP (DHCP enabled), the IP address may change periodically as the DHCP lease expires. Consider using Dyamic DNS (under Network Configuration) so that external users can always find your network (see "Configuring Dynamic DNS (If Needed)" on page 2-14. • If the IP address of the local server PC is assigned by DHCP, it may change when the PC is rebooted. To avoid this, use the Reserved IP address feature in the LAN Groups menu (under Network Configuration) to keep the PC's IP address constant (see "Setting Up Address Reservation" on page 3-9. 4-6 Firewall Protection and Content Filtering v1.0, March 2009
