Using port forwarding does have security implications, as outside users wil
l
be able to connect to PCs on your network. For this reason you are
advised to use specific Virtual Server entries just for the ports you
r
application requires instead of simply using DMZ or create a Virtual Serve
r
entry for “All” protocols, as doing so will result in all connection attempts to
your public IP address will access the PC specified.
If you have disabled the NAT option in the WAN-ISP section, the Virtua

Server function will hence be invalid.

If the DHCP server option is enabled, you have to be very careful in
assigning the IP addresses of the virtual servers in order to avoid conflicts.
The easiest way of configuring Virtual Servers is to manually assign stati
c
IP address to each virtual server PC, with an address that does not fall into
the range of IP addresses that are to be issued by the DHCP server. Yo
u
can configure the virtual server IP address manually, but it must still be in
the same subnet as the router.
