I have an ASA5510 and working with VPN client 4.8, this works fine no issues at all. I have upgrade 1 client to the new 5.0.02 client and I just can not connect and keep getting a 412 error stating remote peer is not responding. All this does is circulate and keeps looking for the gateway... What could the issue be here? I need to upgrade to this client as we will shortly be rolling out vista and only client 5.0 and onwards works on vista.. I have tried on a new install of vista and xp but the client continues to fail..
