Hotel NAT keeps changing my outward IP Address

Description
I can't successfully use WEBMAIL because every time I make an HTTP connection the outbound-visible IP Address changes. In the past five minutes I've had webmail report an incoming IP address of 130.129.65.100, 130.129.65.248, and 130.129.65.10. Unfortunately webmail logs me out every time the IP address changes, and every connection is getting a new IP address. This makes webmail effectively useless. (webmail: https://webmail.mit.edu/ )
Is there any chance of fixing the Hotel NAT to provide more stable IP bindings?
Thanks,

Andrew -
Please note - another hotel network related request.
I suggest we send a message to the attendees list clearly
stating that the IETF is NOT providing room network and that
the hotel has limited resources to accomedate the requests
of our (unusually demanding) community.
Attendees should be encouraged to come down and use the IETF
network, which will be nore likely to meet expectations, and
which we can tune if needed.

I'll note that until *now* the hotel network was working just fine for me. It worked great on Saturday and Sunday, so it's only something that changed *today* that caused it to fail.

They needed more addresses because there were too many connections to serve from the single address they were using; they made this change during the day today.

Derek,
This was due to, prior to today, they were doing NAT/PAT through 1 IP address. Now they are using a /24. This can cause the outbound NAT to change. We offered them a larger block (/22). I will request tomorrow that they configure the NAT with the larger block since, clearly, the /24 is churning. However, this is out of our direct control, and hotel resources are quite limited.

- sigh * Churn. Lovely. Too bad they can't just turn off NAT completely and borrow IETF DHCP ;)
Thanks for offering them a larger block. I'll try to find a workaround for tonight.

Re-numbering the hotel isn't an option, Derek - the TV's are all IPTV. Changing out the addressing scheme, on the fly, in the hotel would have "interesting" effects to the hotel infrastructure. Remember, there are always the public areas and terminal room.

Chris,
I'm sorry you missed the winky-face in my last note. Of course you can't renumber the hotel. I know that, and I was not seriously suggesting it. It was just meant as a little levity, you know, nudge nudge, wink wink, too bad they can't renumber? ;-) <---- notice the winky face again?

Derek,
Can you check this sometime today. When the hotel fixed the problem with PPTP VPN's the toggle to keep all translated IP's from the same host the same was not ticked. It has now been set. So take a look, and let us know if the webmail is now working.
Thanks,
Andrew

Thanks, I'll check later this afternoon. At around 10am it hadn't been corrected but I'll check again later.
Thank you.

FYI, I can verify that it's working again, and I can connect to webmail from my hotel room. Nice work, and thank you!
The unstable NAT also causes Kerberos to fail (well, V4, but MIT's email servers don't support Krb5 yet). So I can't get ANY email from my room at all... :(
