Model 3086 G.SHDSL Integrated Access Device User Guide 6 • Security
The next step in configuring the IAD is adding the default gateway route. Since the WAN IP address of the
3086 modem at the CO site is 192.168.101.2, this will be the gateway for the 3086 modem at the CPE site,
the modem we are currently configuring.
1. Click on IP Routes under Configuration on the 3086 modem’s Menu.
2. Click on Create a New IP Route.
3. Enter 192.168.101.2 in the box adjacent to Gateway.
4. Leave Destination and Netmask both as 0.0.0.0 because this is the gateway default route.
5. Click on Create and the route will be entered.
6. The default gateway can be verified by clicking on IP Routes under Status in the menu.
Configuring the security interfaces
The interfaces and routes have been configured on the 3086 IAD which will function as the firewall. The
Ethernet side of the 3086 will be configured to be an internal security interface whereas the WAN side is con-
figured as an external security interface since it is on “public” side of the modem connection.
1. Click on Security under Configuration on the 3086 modem’s menu.
2. Under Security Interfaces, click on Add Interface.
3. Select Name of the WAN port (ipoa-0) and Interface Type to be external. Click on Apply.
