This router is working great for me in every way except for the problem that I can't make a very simple VPN connection to my campus down the road. I can make the connection at many other locations, just not through this router.
Okay, the obvious question:
Have you tried removing the 4500 from your network, power-cycling your modem, and attempted a VPN to the school without it in the chain?
The router is in your home, not in the school, correct? Are you connecting wired or wirelessly?
I am running FW:1.02, but I am able to VPN out with what seems to be a more restrictive environment.
Use Unicasting: Off
Enable DNS Relay: Off
UDP: Address Restricted
TCP: Port & Address Restricted
Anti-spoof checking: On
All ALG Configs: On
Multicast Streams: Off
If I am hosting the VPN session, I do add the appropriate Virtual Server settings, but nothing onerous.
Let us know if a direct connection from your home works.
