Cant get ip phone connected to BCM.

[NTL555]

Hello,

I am having difficulty forwarding/connecting an external IP address such as 66.137.144.xxx to my internal IP address of 192.168.100.20.

Currently using a Linksys router WRTG54 for testing purposes and a cayman DSL Modem from SBC (static IP Addressing). The BCM is on the DMZ and its pages can be accessed (Unified Manager, installed clients, etc) from several different place such as New York, Dallas, Houston, California, and Florida. I had friends type in the address.

When I plug in the IP Phone, I put in my local address, subnet, gateway, my S1 address (66.137.144.xxx), port number 7000, and do the same for s2, and then hit ok for the rest of the options... It connects and just displays 01/01 12:00AM. I wait for several minutes even an hour and still its at the same display. Still no connection to the BCM.

If I connect locally, the phone comes up fine, asks me for my registration password, gives me an Auto Assigned DN Number, and gives me my advertising logo.

If I configure the BCM to the External IP of 66.137.144.xxx, then I can get a phone to boot up with no problems remotely. The reason why I can not do that is because I need to use the LAN CTE client on the internal side.

What can I do? Any suggestions?

IS your published IP address for VOIP set to LAN 1 or LAN2?

It'll need to be LAN 2 in order for IP phones to register to the IP address on the second NIC.

I would strongly recommend a VPN for your application - by putting the BCM on the Internet with a public IP address, you're practically standing on your front doorstep asking the hackers to come get you.

My published IP address is LAN 1 which is 192.168.100.20. My external static IP address 66.137.144.xxx is set to my Linksys router to which I placed 192.168.100.20 in the DMZ. My LAN 2 address is the default IP of 10.10.11.1.

Internally my I series phones can connect to LAN 1 (192.168.100.20) perfectly fine. When I plug in the IP Phone, I put in my local address, subnet, gateway, my S1 address (66.137.144.xxx), port number 7000, and do the same for s2, and then hit ok for the rest of the options... It connects and just displays 01/01 12:00AM. Never connects. Thats my problem.

THanks.

IP phones won't work through NAT unless the firewall is fully cone NAT compliant.
