For IP based cameras using this router, and making them viewableto the outside world, you can use one of these two options. These suggestions are from Actiontec's website. Also on the main router screen, there is a section in there about setting it up to use a camera.
Set up Static Network Address Translation
A static NAT allows devices behind a firewall and configured with private IP addresses appear to have public IP addresses on the Internet. This allows an internal host, such as a web server, to have an unregistered (private) IP address and still be reachable over the Internet. To set up Static NAT:
1. Open a Web browser and enter "http://192.168.1.1" in the Address bar, then press the "Enter" key on the keyboard. Click OK.
2. Select Static NAT from any "Security" screen. The "Static NAT" screen appears.
3. Click Add. The "Add NAT/NAPT Rule" screen appears.
4. Select a source address from the drop-down list. Usually, this is the public IP address assigned by the ISP.
5. Select a "Destination Address from the appropriate drop-down list.
6. Select the protocol that needs to be accessible from the public IP address from the "Protocol" drop-down list.
7. From the "Operation" drop-down list, select ‚"Static NAT" or "NAPT" (Network Address Port Translation), depending on the type of rule.
8. Define when this new rule will occur from the "When should this rule occur?" drop-down list.
9. Repeat these steps to add more static IP addresses from the network.

Use a DMZ (Demilitarized Zone) Host
The DMZ host feature allows one device on the network to operate outside of the protection of the firewall. This can be used:
• To use an Internet service, such as an online game or video-conferencing program, that is not present in the Port Forwarding list and for which no port range information is available.
• To expose one computer to all services without restriction or security.
Warning: A DMZ host is not protected by the firewall and may be vulnerable to attack. Designating a DMZ host may also put other computers in the local network at risk. When designating a DMZ host, consider the security implications and protect it if necessary.
To designate a local computer as a DMZ host:
1. Open a Web browser and enter "http://192.168.1.1" in the Address bar, then press the "Enter" key on the keyboard. Click OK.
2. Click Security, then select DMZ Host from the left side of the screen. The "DMZ Host" screen appears.
3. Click in the "DMZ Host IP Address" check box, then enter the IP address of the computer to be designated as a DMZ host. Note that only one network computer can be a DMZ host at any time.
4. Click Apply. Click in the "DMZ Host IP Address" check box again to disable the DMZ host.
