VPN via PIX 515e

[iiiiss]

HI !

I have a problem setting up a VPN connection via my PIX 515e. I´m using the cisco VPN client Version 5.2.3
and this is my configuration of the PIX. I think I must have overlooked something basically. Every help would be appreciated.

THX

BTW

I´ve forgotten to tell that I try this in a simple LAN for practising. Just 2 workstations. For some seconds the connection seems to work but after a few seconds the client says no connection .

THX a lot for every help

OH.. another thing I´ve forgotten. During the connection attempt the PIX displays a lot of those messages. What exactly does that mean or where is my problem ?

THX a lot

Here's two ideas:
1. Try using the 3.x version of the client.
2. It seems the remote connections are attempting to use DH group 1. This PIX is configured to use group 2.

hope this helps,
