8.7 Virtual Server
For example: Specific ports on the WAN interface are re-mapped to services
inside the LAN. As only 69.210.1.8 (e.g., assigned to WAN from ISP) is visible to
the Internet, but does not actually have any services (other than NAT of course)
running on gateway, it is said to be a virtual server. Request with TCP made to
69.210.1.8:80 are remapped to the server 1 on 192.168.0.2:80 for working days
from Monday to Friday 8 AM to 6PM, other requests with UDP made to
69.210.1.8:25 are remapped to server 2 on 192.168.0.3:25 and always on.
You can setup the router as Index 1, protocol TCP, interface WAN1, service
name test1, private IP 192.168.0.2, private port 80, public port 80, schedule
from Day Monday to Friday and time 8:0 to 16:0 and index 2, protocol UDP,
interface WAN1, service name test2, private IP 192.168.0.3, private port 25,
public port 25, schedule always.
Click Virtual Server to configure the parameters.
