VoIP/(802.11g) ADSL2+ (VPN) Firewall Router
Chapter 4: Configuration
134
Example: Remotely Access Router GUI
If you wish to remotely access your Router through the Web/HTTP at all times, you would need to enable
port number 80 (Web/HTTP) and map to Router’s IP Address (192.168.1.254).
Then all incoming HTTP requests from you (WAN side) will be forwarded to the Router IP address of
192.168.1.254.
Port number 80 has already been predefined, so you can set this up simply by clicking on Helper.
A list of predefined rules window will pop up and you may and select
HTTP_Sever
.
Application: HTTP_Sever
Time Schedule: Always On
Protocol: tcp
External Port: 80-80
Redirect Port: 80-80
IP Address: 192.168.1.254

If you have disabled the NAT opti
on 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
configurin
g 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.
Attention
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
attempting to access your public IP of the DMZ PC specified.
