I have a Sonicwall TZ170 hooked to a remote network. I have configured it to pass port 3389 from WAN to LAN/[designated inside IP's] and from LAN[designated IP's] to WAN. I can ping the firewall, which sits on a public address. The Sonicwall GVPN client connects just fine. But from there I cannot Remote Desktop to any systems (their firewalls are off, there is no local IP filtering, and RD is enabled). For that matter, with the GVPN client connected I cannot ping any inside addresses by number or name (NetBIOS pass-through is enabled). Otherwise the firewall seems to work fine. I have been all over Microsoft and Sonic's websites looking for the answer, but can't find it, so I thought I'd see what the experts think. Is there a complimentary protocol required? Both TCP and UDP are allowed on 3389. I could sure use some suggestions. Thank you.
