does have security implications, as outside
users will 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
your application requires, instead of using DMZ. As doing so will result
in all connections from the WAN attempt to access to your public IP of
the DMZ PC specified.
If you have disabled the NAT option in the WAN-ISP section, the
Virtual 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 static 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. You can configure the virtual server IP address
manually, but it must still be in the same subnet as the router.
