I've been fighting this all weekend, and cannot seem to get it to work for the life of me. I'm unable to establish a VPN connection via the default Windows client to my Cisco Router (2621XM, IOS 12.4).
I have followed many different guides, all of which have nearly 100% identical co0nfigs, but the one that closest resembles my current config is:
I am using a Win2k8 Radius server, but I also need to point out that when I set "aaa authentication ppp default local" and take out the radius form of auth, I'm still stuck in the same problem.
On debugging the Raidus authentication, It's informing me that the authentication failed. no matter what username I use.
Any ideas on what I can throw into the mix here to get this working?
