SonicWall PRO 330 VPN Issue

Archived from groups: comp.security.firewalls (More info?)

We have several mobile users that need to access an IP-protected
application online. I am trying to configure our SonicWall PRO 330
(firmware 6.5.0.4) to allow remote users to connect via VPN and then
browse with all traffic being routed through the firewall so that the
traffic appears to originate from the LAN segment and therefore will
go out through the NAT public IP of the firewall. I have tried to set
Default LAN Gateway under VPN -> Advanced Settings to the LAN IP of
the firewall (192.168.1.1) and checked Set Default Route As This
Gateway under VPN -> Client Settings and it does not work. No matter
what combination I try, clients either cannot surf at all once
connected to the VPN or can connect successfully to the VPN but use
their default gateway (not the firewall) as the route for all traffic.
As it stands right now, the VPN allows mobile users to access
resources on the LAN segment, so that part works, but I need to fix
the source IP issue.

I have contacted SonicWall support about this and the first rep.
suggested that I try the settings I explained above and the second
rep. told me that the PRO 330 did not support this and I would need to
buy a model with two WAN ports, which does not sound reasonable.

Any help would be appreciated greatly!
