We have a remote office with several users. The users connect to the cable modem there and individually VPN to our NSA2650 via Sonicwall Global VPN client. This client is set to tunnel-all mode because of cookie and session stuff. Unfortunately, when the VPN is connected, the local printer at the remote office is not accessible because all of the traffic is being tunneled. The VPN client takes over the network interface and not even pinging the printer works. I got on with support and they said it was impossible. It looks like other manufacturers have split-tunnel or similar functionality, but Sonicwall support confirmed there was no way to do something similar with their firewall.
Is there a way to create a static or other route on the machines that would allow traffic to reach the printer while the VPN is connected? NB: the VPN and LANs are on different subnets.
