Billion 400G Router
Chapter 4: Configuration

Example:
If you would like to remotely access your routers’ Web/HTTP interface all the time, you would need to enable
port number 80 (Web/HTTP) and map it to the Router’s LAN IP Address. All incoming HTTP requests on the
WAN network will then be forwarded to the router’s IP address of 10.0.0.2. Since port number 80 is already a
predefined rule, click Helper in the Application section. A predefined rules window will pop and you can select
HTTP_Sever.
Application: HTTP_Sever
Time Schedule: Always On
Protocol: tcp
External Port: 80-80
Redirect Port: 80-80
IP Address: 10.0.0.2
Add: Click it to apply your settings.
Edit/Delete: Click it to edit or delete this virtual server application.
If you have disabled the NAT option in the WAN-ISP section, the Virtual Server
function will not work.
If the DHCP server option is enabled, you have to be very careful when assigning the IP
addresses of virtual servers so that you avoid conflicting IP addresses. The easiest
method of configuring Virtual Servers is to manually assign static IP address to each
virtual server Computer, with an address that does not fall into the range of IP addresses
that are to be issued by the DHCP server. These manually configured IP addresses MUST
still be in the same subnet as the router.
Attention
Using port forwarding has security implications, since outside users will be able to
connect to Computers on your network. For this reason you are advised to add
specific Virtual Server entries only for the ports that your application actually
requires, instead of using the DMZ function. Using the DMZ function will result in all
connection attempts from the WAN network having access to the public IP specified
in the DMZ config section
