hehe yeah thats an old problem :) your remote person is on a network that is performing NAT, it breaks the natting of traffic that should be traveling down the VPN tunnel

If a VPN connects and no traffic flows then the problem is usually NAT - either the nat 0 command is missing or you need to add the command above - I looked at your config and you had ..

nat (inside) 0 access-list inside_nat0_outbound

that matched an ACL that matched your VPN IP Pool so the next logical thing was Nat-traversal

Glad to help - put your feet up and have a coffee :)
and ThanQ
