Local End IP: This is the end Inside Local IP Address (ILA). If your rule is for all local IP
addresses, then enter 0.0.0.0 as the Local Start IP address and 255.255.255.255 as the
Local End IP address. This field is N/A for One-to-one and Server mapping types.
Public Start IP: This is the starting Inside Public IP Address. Enter 0.0.0.0 here if you have a
dynamic IP address from your ISP.
Public End IP: This is the ending Inside Public IP Address. This field is N/A for One-to-one,
Many-to-One and Server mapping types.
Note:
Using port forwarding 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.
Attention:
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.
