Once you have determined which PCs need to support which
services, follow the steps below to configure the router to map
the required ports to the host PC:
1. Assign a fixed IP address to the PC you want to set up as a
service host (see Configuring a Fixed IP Address for a PC on
page 45). Record this IP address.

2. Open a browser window and login to the router.
3. Click Firewall/Security, then Port Mapping. This displays
the Port Mapping screen (see Figure 20), which shows the
status of existing port mappings. When you first open this
screen, it will be blank except for the Enable field and the
buttons at the bottom of the screen.

4. In the Port Mapping field, select Enable. This will enable
all port mappings.
