ADD/EDIT VIRTUAL SERVER

In this section you can add an entry to the Virtual Servers List below or edit an existing entry.

Enable:

Entries in the list can be either active (enabled) or inactive (disabled).

Name:

Assign a meaningful name to the virtual server, for example Web Server. Several well-known types of virtual server are available from the "Select Virtual Server" list. Selecting one of these entries fills some of the remaining parameters with standard values for that type of server.

IP Address:

The IP address of the system on your internal network that will provide the virtual service, for example 192.168.0.50.

Protocol:

Select the protocol used by the service.

Private Port:

The port that will be used on your internal network.

Public Port:

The port that will be accessed from the Internet.

Inbound Filter:

Select a filter that controls access as needed for this virtual server. If you do not see the filter you need in the list of filters, go to the ADVANCED -> Inbound Filter screen and create a new filter.

Schedule:

Select a schedule for when the service will be enabled. If you do not see the schedule you need in the list of schedules, go to the TOOLS -> Schedules screen and create a new schedule.

Save:

Clicking Save saves the new or edited virtual server entry in the following list. When finished updating the virtual server entries, you must still click the Save Settings button at the top of the page to make the changes effective and permanent.

VIRTUAL SERVERS LIST

The section shows the currently defined virtual servers. A Virtual Server can be changed by clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and the "Edit Virtual Server" section is activated for editing.

You might have trouble accessing a virtual server using its public identity (WAN-side IP-address of the gateway or its dynamic DNS name) from a machine on the LAN. Your requests may not be looped back or you may be redirected to the "Forbidden" page.

This will happen if you have an Access Control Rule configured for this LAN machine.

The requests from the LAN machine will not be looped back if Internet access is blocked at the time of access. To work around this problem, access the LAN machine using its LAN-side identity.

Requests may be redirected to the "Forbidden" page if web access for the LAN machine is restricted by an Access Control Rule. Add the WAN-side identity (WAN-side IP-address of the router or its dynamic DNS name) on the ADVANCED -> Web Filter screen to work around this problem.
