I have my VOIP (Innomedia DVC with Phonom) working great in the "supported" configuration: DSL modem, then DVC (configured with static IP), then wireless router (configured as a DHCP client). Internet and phone work great. However, I recently tried using VPN and the VPN isn't connecting.
I suspected the DVC was causing the VPN problem so I tried taking out the DVC. To get my Internet connection to work after taking out the DVC I had to change the router configuration from DHCP client to static IP. Well that did fix my VPN.
Now to get my VOIP working again. I thought I could put the DVC "behind" the router (i.e. switch the position of the router and the DVC from what I had before). I configured the DVC to be a DHCP client instead of a static IP. However, while all the lights were normal, I couldn't get a dial tone. I tried calling Phonom and they said while they believe it is possible to do what I'm trying, they won't give me any help with it. Anything I may be forgetting?
