What is better option for VPN clients access public Internet while they are connected to VPN Concentrator?
Split tunnel is the one, but not recommended due to security risk. Using "Tunnel Default Gateway" on Concentrator and tunnelling everything from VPN client is another option. But in this way, VPN clients can not access the other private LANs over LAN-to-LAN tunnels through this concentrator since the lack of hairpin routing capability on VPN Concentrator release 3.6.
Release 4.1 can provide a filter to overwrite tunnel default gateway. Dose this mean that Concentrator can route Internet accessing traffic from VPN Client to tunnel default gateway which is the PIX and also can route tunnel traffic from VPN Client to other LAN-to-LAN tunnels?
