Hello,
    I am trying to set up an ISA 2004 VPN behind a Verizon ActionTec Fios router. I have the ISA configured and the routers firewall turned all the way down, but I still do not get any connection. I assume I have to do some routing for any traffic coming to 1723, but I am not sure how to do that.

You would have to go into the application section of the router, then to port forwarding.   From there you would forward port 1723 to the internal IP of your ISA server.

On a side note, I tried doing this and had some problems with the Verizon router, the port forwarding kept flaking out.   I ended up replacing it with a Cisco ASA5505 to handle my firewall and VPN requirements.   Contrary to what verizon tells you, you can replace the router with an off the shelf model.

It says that the hostname cannot be resolved if I use the internal IP of the server. The only way it resolves and goes to active is if I put the IP for the adapter plugged right into the router.

Also, do I need to use the "Specify public address" checkbox and put the routers public ip?

I managed to set up VPN and I am able to connect to it, but once I have done this I am unable to browse either the internet or the remote network. In Vista it gives me a "limited connection" error. XP does not give me this error, but the result is the same.
