Or you can assign VPN clients the autonet address in your VPN server
configuration. I'm preparing an article on how to do this.

Why not just create two VPN's, one with 1 subnet and the other one with
another subnet, you won't have this problem again no matter on which
hotel your customer stay.
For us OWA/RPC HTTP don't work because we use RSA to authenticate user
on OWA.

Subject: [isalist] Re: Error establishing a VPN to the ISA server
Until the one you switch to is on a 10. network and all the work Tom did
with the internal IP stuff is all for naught. ;)
I'm telling ya... This is becoming way more and more common. I'm
surprised to see this dude's hotel on 192.168.110 (I really am) but it's
actually becoming more common for some of my people to be on conflicting
nets, particularly when they give you a 10.0.0.0 address on a 255.0.0.0
subnet. Hence the need for a localized NAT solution- OWA/RCPoHTTP is
fine when all you need is email stuff, but when you've got to be RDP'ing
into multiple servers, accessing SQL boxes, hitting VoIP equipment,
etc., publishing scenarios just don't cut it...
I've tried lots of different things at varying degrees of complexity
(like a virtual pc install, Kerio routing tricks, KY jelly, etc) but
I've found that keeping things limited to the "plug THIS into THAT, then
plug THAT into the OTHER THING" mentality is the best.
That's really why most of my mobile people have the high speed EVDO
solutions (we use verizon) so that we don't really have to worry about
it. Hotel connections are usually way faster, but EVDO works all the
time (most of the time, anyway).
I can actually envision a market for a little USB device that NAT's the
connection all the time for the true "road warrior" that spends a lot of
time on other people's networks.

You'll still hit it. The router will be given the local IP just like a
lappy would, and you'll hit it via the NAT'd connection. Do it all the
time.

Plan is, I am going to take;
1.
2. A linksys 4 port BB router, to plug in between the hotels BB,
and his notebook, which I think will do the trick nicely.
3.
4.
5. A wireless broadband card, just in case.
6.
7.
8. A second notebook with the companys SOE on it, also just in
case.
9.
10.
11. My Wife, it will be a nice little day or two away for us.
