RE: VPN Question

["Dana Smith" <dana_smith () comcast net>]

This is likely caused by the hotel blocking IPsec traffic, which a number of
them do. It's a crap shoot as to which ones block it and I don't believe
there is an easy workaround with Sonicwall. You will probably need to
consider deploying another VPN client product that allows for alternate
protocol VPN traffic.

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?

Good afternoon all,

This posting is a little off track, but I'm hoping someone can help me
anyway.

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.

Thanks,

Jim Brezicky
