I'm assuming that you have a private/internal IP address pool for the VPN 
clients, correct?  Is the network range for that pool included in the SA 
used to build the LAN to LAN tunnel to the remote site?  If the client 
pool range isn't in the SA, the ASA on your end will never try to send 
that traffic over the tunnel to the remote site, which could explain why 
you see nothing after the initial outbound attempt.

That's just a guess, but I've seen it burn people before :(
