My network consists of an 871 router, 48 port Switch, 2006 WLAN Controller, 1231 APs, and SonicWall VPN.
VPN connections are fine if the client is using the wired network. VPN connections do not work if the client is wireless. I've had a couple of suggestions...VPN Passthrough on the WLAN Controller - that didn't work, but I'm not sure I had the right gateway. And they also suggested changing the MTU size on the wireless card in the laptop. Still trying to figure out how to do that.
Any other ideas? This seems like it should be a fairly easy fix.
Are your wireless clients getting an IP? That is are you using the SonicWall as your DHCP server for the wireless clients?
If so it will probably not work. There is something with the SonicWalls that they don't support. I went round and round with SonicWall and couldn't get DHCP working for wireless clients coming through Cisco WLC Controllers.
