Port mapping / Virtual Servers The Port mapping / Virtual Servers configuration section is where you can configure virtual servers (such as a LAN Web server) on the LAN or DMZ Interfaces to be accessible through the WAN. One may also regulate how bandwidth management (traffic shaping) is applied to traffic flowing through the WAN interface of the firewall to the LAN or DMZ. It is also possible to use Intrusion Detection / Prevention on Port mapped services. These are applied in the same way as with policies. See the previous chapter for more information. Mappings are read from top to bottom, and the first matching mapping is carried out. Add a new mapping Follow these steps to add a new mapping on the WAN interface. Step 1. Click on the Add new link. Step 2. Fill in the following values: Name: Specifies a symbolic name for the rule. This name is used mainly as a rule reference in log data and for easy reference in the policy list. Source Nets: Specify the source networks, leave blank for everyone (0.0.0.0/0). Source Users/Groups: Specifies if an authenticated username is needed for this mapping to match. Either make a list of usernames, separated by a comma (,) or write Any for any authenticated user. If it is left blank there is no need for authentication for the policy. Destination IP: Leave empty to use the WAN IP of the firewall, or enter an additional IP address to be forwarded to the specified Pass To address. Service: Either choose a predefined service from the dropdown menu or make a custom service. Pass To: The IP of the server that the traffic should be passed to. Schedule: Choose which schedule should be used for this mapping to match. Choose Always for no scheduling. Step 4. If using Traffic shaping, fill in the required information. If not, skip this step. Click the Apply button below to apply the changes or click Cancel to discard changes. Note: Refer to Appendix C of the manual for details on mapping Public IP addresses to Internal Servers. 34
