Virtual Server tab
The virtual server tab configures port-forwarding rules, which makes services on the LAN accessible from
the WAN. Virtual Server configuration is only accessible when the SU is in Routing mode.
Forwarding rules
Enabled:
A rule can be either enabled or disabled, if disabled it will be
in the list but it will not be activated.
Name:
You can give the rule a name to easier remember what it does.
Private IP:
This is the IP-address of the LAN unit to which the traffic is
forwarded.
Protocol:
You can choose if you want to forward TCP, UDP or both
protocols to the specified private IP.
Single/Range
The rule can either specify a range of ports or a single port to
forward. If range is used the same range is used for both LAN
and WAN side. If single is used you can alter the port.
Single
Public port:
This is the port on the WAN side. Traffic against this port will
be forwarded according to this rule.
Private port:
This is the port on the LAN side. Traffic against the above
public port will be forwarded to this private port.
Range
Start port:
This is the first port in the range that will be forwarded.
End port:
This is the last port in the range that will be forwarded.
To add a new rule enter the above parameters according to your needs. For example if you have a FTP
server running on a PC connected to the LAN side you need to:
1.
Check the IP-address of the PC. A good choice is to configure a static address on PCs that have
services that should be accessible from the WAN. Choose an IP-address outside the CPEs DHCP-
server scope, (configured under network tab).
2.
Give the rule a name.
3.
Fill in the IP-address of the PC in “Private IP” field.
4.
Choose single
5.
Enter 21 in “private port” and “public port”.
6.
Save the rule, by pressing the save button.
7.
To activate the rules you need to press the Apply button.
