Solved: ASA 5505 and VPN

ThaMaster · ‎01-29-2009

I have a ASA 5505 and want to configure a VPN connection. I have already configured it but I'am having trouble with the connection. I want dat normal local LAN or Internet traffic goes to the internal LAN and only traffic to the company goes trough the tunnel. Now I can only connect to my local LAN. Can someone help me?

This is my configuration:

hostname asa00

By local LAN do you mean the one you access through the tunnel or the LAN local to the client that's initiating the vpn connection?

In any case you should have nat-traversal turned on.

crypto isakmp nat-traversal 3600

Hope this helps.
