I have looked around this topic:
"Cisco VPN secure vpn connection terminated locally by the client eason 412: the remote peer is no longer responding"
but so far I have not found a solution for my problem, this is my scenario:
I have several clients working with cisco vpn clients without problem, but I have one particular user that can't connect to my ASA, my VPN configuration was modified to have these service in port 80, as I said before, all users are working and only one is having problems, after check and troubleshoot, I have found that this user is not able to do a ping to my IP(all other can do ping), I check that he can go to any web site, so port 80 is open :) , but ping is not enabled.
My question: Cisco VPN client need to perform a ping to check if the peer is up when he is establishing the connection?
Thanks for your help guys
