I have been trying for the last couple of days to get VPN working over L2TP from a 10.4 Powerbook to a 10.4 Server through a Linksys router. I have the Cable/DSL Router on the receiving network set to forward UDP ports 1701, 4500, and 500 to the internal OS X Server running VPN. The connection/authentication works great, however once I am connected through VPN, I only have access to the VPN server and not other devices on the network that I am connecting to. Nor am not able to ping the other IP addresses on the network.
What am I missing?
Thanks.
