D-Link DI-711 wireless gateway behind Sonicwall firewall

[baseband]

My company has a Sonicwall SOHO3 acting as both a firewall and a VPN server for users to access our internal network from home. We have a D-Link DI-711 wireless gateway that we wish to use to provide wireless service to several employees. Optimally, I would have liked to put it in front of the firewall and require users to VPN in to the Sonicwall. Unfortunately, the D-Link supports PPTP passthrough, but not IPSec, so I guess this isn't an option.

So I decided to put the D-Link behind the firewall, use WEP, and forget about wireless users authenticating to the VPN (unless there's some easy way to do this that I haven't thought of). So I set it up and I was able to ping hosts on the local network and the Sonicwall, but I couldn't get past the Sonicwall to the Internet. I tried several things, including putting the D-Link on its own subnet and making static routes back and forth between it and the Sonicwall, but that didn't work.

Is there something I'm missing here? The guy I talked to from D-Link told me to put the wireless gateway in the Sonicwall's DMZ, but I'd rather not deny my wireless users the firewall services offered by the Sonicwall. Plus, the guy kind of sounded like he didn't know what he was talking about and was just trying to get rid of me.

Anyone have any ideas?

Nevermind. After some more problems popped up that weren't there yesterday, I called D-Link again. After an hour of the same troubleshooting I'd already done, they gave me an RMA number.
