I've been trying to configure an L2TP VPN for our company remote employees to use VPN in hotels around the world as the Cisco VPN ports are often blocked.
I've used Cisco's own L2TP examples, and examples from various forums. All have the same response: The external PC gets an ARP reply from the PIX but nothing else when trying to connect. (Our 2nd PIX using Cisco VPN works fine)
Below is the important bits of the running config. Can anyone tell me the (probably obvious) thing I have missed or done to stop it working.
Thanks
