I know you can do this on the enhanced OS but I can't find the option any where for the standard OS. It seems it just automatically uses the LAN subnet that is behind the SonicWall. I'm making a L2L VPN tunnel with a ASA 5510 and only have a few host on each side that need to use the tunnel.
I know ACLs is an option but I rather just classify the interesting traffic as the host that need access across the tunnel.
