I am trying to setup a vpn connection using Cisco vpn client 4.6 and PIX 6.3. My problem is when I try to connect from the client, I get an error message says that “Unable to connect with the remote device"

My pix outside is connect to a internet router and i can ping my default gateway from the pix. I am using correct vpngroup and password on the client.

I don't know what is wrong with my config. Please help. Below is my config.

Thanks in advance.

Regards,

Asif

Try adding ipsec "esp-md5" transform set, and also an md5 isakmp hash.

You need to make sure that the PIX and the client agree on both ipsec and isakmp configs.

Can you enable logging on the client and set it to log all messages and post it here?
