I had PIX515E Restricted with three interfaces running at 7.0.6. Had a L2L VPN and a couple remote access VPN tunnels operating on this PIX.
I replaced the PIX with another PIX515E unrestricted with more interfaces. This replacement PIX runs at v7.2.1. I tftped the config from the old pix over and added the new interfaces and their corresponding ACLs.
Everything worked fine including the L2L tunnel, except for the remote access vpn. As soon as the IKE phase one finished and user authenticated, the Pix dropps the connection. VPN client is v.4.6.03.
I tried removing all RA VPN commands and started over. Tried simplifying the authentication from RADIUS to just local user. Tried usnig ASDM and its VPN wizard to remove and config the RA. It had problem removing and applying the VPN statements, though web console user is given priv level 15. I had to manually implement commands generated in ASDM wizard. Nothing worked.
Please see attachment for detailed PIX debug log.
