VPN & VoIP

I have a 3005 VPN Concentrator. I have a remote location coming in over DSL to the concentrator with a PIX 506 on the remote side. I am having trouble getting my IP phone to work at the location. Here is an example of what is going on. From a client PC, I can ping 172.17.0.50 - the default gateway of the main location. I cannont ping 172.17.1.50 - the default gateway for our IP phones on the network. (the primary carrier is 172.17.1.250). All of my routes are set up as 172.17.0.0 255.255.0.0. I am unsure why I am unable to ping the 172.17.1.xx addresses, as they should be following upon the same rules as the 172.17.0.xx. Any help would be appriciated. Thanks in advance!

Re: VPN & VoIP

Hi

It will be better if you can throw more lite on the exact problem which you are facing currently over there.

It can help to a great extent if you can post out a topological figure representing the connecitivity you have in place with the ip address details.

Re: VPN & VoIP

Unfortunatly, we are a financial institution, so that keeps me from being able to give you exact details. Here is a bit more to go on though:

The network at my remote location is 172.17.3.0/24

It comes in over my 3005 VPN Concentrator. My router behind the concentrator is 172.17.0.50, but also has a secondary IP on the same interface of 172.17.1.50 - this range is for our IP phones. When at a PC from the remote location, I can ping 172.17.0.50. I cannot ping 172.17.1.50. All of my routes are listed as 172.17.0.0 255.255.0.0. I am unsure why this will not allow this to go through. I figure if I get my ping running, my phone should light up too.

Thanks for your help!
