NAT
NAT stands for Network Address Translation, a process which converts private IP addresses of a computer on the internal private
network to one or more public IP addresses for the Internet. NAT changes the packet headers to the new address and keeps track
of each session; when packets come back from the Internet, it performs the reverse conversion to the IP address of the client
machine.
Virtual Servers
Virtual Server allows you to direct incoming traffic from the Internet to a specific computer in your local network. A maximum 32
entries can be configured.
Click Add to create a Virtual Server.
As an example, to setup a web server on a computer using 192.168.1.88 as its IP Address, select HTTP as Service and enter
192.168.1.88 as the Server IP Address. Otherwise if the service you want to setup is not available from the Select a Service drop-
down list, you can define your own Virtual Server.
1. Enter the IP Address to forward the incoming connections to.
2. Enter the External Port range for the incoming connections
3. Select the appropriate protocol
4. Enter the Internal Port Range
Click Save/Apply to save the new Virtual Server configuration settings.
