There is no work around for the problem. You can change your internal VPN addresses to a not so common subnet which will reduce the possibility of it from happening. Example: If the hotel use 192.168.1.x/24 subnet and your internal domain for your VPN is the same subnet you will have a routing and VPN tunnel problems.

If it works in some and not in others, it means in this case that the source is the problem. Unless you have round robin VPN IP addresses and your users do not know what the IPs are? Which I highly doubt and why would you want to do this?

I have a SonicWall Pro230 and I'm trying to do VPN with it. My users connect from some locations and not others. Example: They could connect from the Airport in Cincinnati, but not the airport in Las Vegas. Seems they can't connect in many (if any hotels). In speaking with SonicWall they said this is a known issue when connecting through a firewall on the hotel side. I know I'm not the first company to try this, and was wondering how others get by this issue? Or is this an inherent SonicWall issue. Most of my users are traveling Sales people, and will go all around the US, and Japan. Any insight would be GREATLY appreciated.
