Please, I've been working on this for a few weeks now, and have had to learn everything pretty much on my own, because no one can seem to give me an answer and help me. No one has even replied to 3 different posts about this subject, so I'm trying it in here.
Here's the situation. I have 2 1760 routers with DSPs, FXO, & FXS cards. They both have the on-board Fa 0/0 interface. I'm tieing two key systems together via VoIP trunks with these routers. I've completed the VoIP programming and it is working as expected. I'm now trying to implement a site-to-site VPN tunnel for these two routers and the VoIP traffic to go through.
I'm not sure if it can be done with just the onboard fa 0/0 interface, and no real LAN behind it. These routers will be on an existing network, however, they will be obtaining(static) a 2nd WAN IP to connect to the outside world only for VoIP traffic between the two.
Please...I'm not Cisco genius and I need some help. I've got probably 20 docs on configuring VPN, but I need some help and questions answered. I'll send my config if anyone needs to look at it.
