Local End IP: This is the end range for 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 start range for 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 end range for Inside Public IP Address. This field is N/A for
One-to-one, Many-to-One and Server mapping types.
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
.
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.
