The IP address of the system on your internal network that will provide the virtual service, for example
192.168.0.50
. You can select a computer from the list of DHCP clients in the "Computer Name" drop-down
menu, or you can manually enter the IP address of the server computer.
Protocol
Select the protocol used by the service. The common choices -- UDP, TCP, and both UDP and TCP -- can be
selected from the drop-down menu. To specify any other protocol, select "Other" from the list, then enter the
corresponding protocol number (as assigned by the IANA) in the Protocol box.
Private Port
The port that will be used on your internal network.
Public Port
The port that will be accessed from the Internet.

Virtual Server List
This is a list of the defined Virtual Servers. Click the Enable checkbox at the left to directly activate or
de-activate the entry. An entry can be changed by clicking the Edit icon or can be deleted by clicking the
Delete icon. When you click the Edit icon, the item is highlighted, and the "Edit Virtual Servers" section is
activated for editing.
Note: 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.
