Jim, Hospitality Industry does not have a standard for providing HSIA (High Speed Internet Access). In my experience working a wile in major hotel chain, only in last year HSIA became a major issue. However, here some tricks: 1. Keep a web browser open during the VPN session. Some HSIA servers drop your IP as soon as you close the web browser or e-mail client. 2. Renew an IP address right before connecting to VPN server. Some servers will renew IP addresses after short time, I so as little as 15 minutes. 3. Make sure that you can accept multiple independent session from same IP address. Usually hotels "NATing" IP addresses. If you have two users trying to connect from same hotel most of the time you will have one IP address connecting to you. I am skipping cases where telephone cable connected to nics and such. Report an incident to manager, they maybe know some tricks. On Friday 22 August 2003 16:31, DeGennaro, Gregory wrote:
Jim, This is a hotel issue. 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.
