If you have disabled the NAT option in the WAN-ISP section, the Virtual
Server will hence become invalid. If the DHCP option is disabled, you
have to to be very careful in assigning the Ip addresses of the valid
servers in order to aviod conflcits. The easiest way of configuring Virtual
Servers is to manually assign static IP addresses to each virtual server
PC,with an address that dees not fall into the range of IP address that are
issued by the DHCP server. You can configure the virtual server IP
address maually, but it must still be in the same subnet as the router.
Using port mapping does have security implications, since outside users are
able to connect to PCs on your network. For this reason you are advised to
use specific Virtual Server entries just for the ports your application requires
instead of simply using DMZ or creating a Virtual Server entry for “All”
protocols, as doing so results in all connection attempts to your public IP
address accessing the specified PC.
