Re: [FW-1] Securemote crashes Win2k when used at my outlaws house (AT&T is the ISP).
VPN blocking is just that-- blocking. As in you get nowhere. No
authentication, no communication, nothing. Zip. Zero. It's accomplished
by blocking the ports and/or protocols needed to facilitate the connection.
That said, the fact that you can authenticate immediately rules out a
blocking scenario. You *are* getting a VPN connection established. If you
were being blocked you wouldn't even get that far.
The fact that it blows up when you actually try to use it is interesting,
but it's unlikely that it's due to the ISP. They can't see inside the
packet (it's encrypted, that's the whole point) so they can't be responding
to content. They aren't blowing out you out based on seeing an encrypted
packet, because if they were, you'd get blown out earlier in the game
(authentication time).
Throw in that I have yet to hear of a technique for producing the particular
STOP error you describe via network poking... and... well... you get the
point.
That DRIVER_IRQL_NOT_LESS_THAN error you're getting is a stock Windows
NT/2000 condition that crops up in a lot of different scenarios, most of
them having nothing whatsoever to do with SecuRemote or even with VPNs.
It's generally either a hardware issue, a driver issue, or both. In your
case I'd be asking whether there was anything unique to that location (a NIC
or instance of same that you use there but nowhere else?) at the hardware or
driver level.
Good luck...

Subject: [FW-1] Securemote crashes Win2k when used at my outlaws house (AT&T
is the ISP).
Hey people,
I use my laptop from many locations around the country (therefore multiple
ISP's as well), and Securemote works well everywhere, except for here at my
outlaws house in New Hampshire.
I use Securemote build 4200 with strong encryption, with IKE as the
encryption scheme.
I've heard that ISP's can disable VPN use via their cable lines somehow, to
force users to upgrade to a business package. The ISP they use here in
Kensington New Hampshire is AT&T.
I can authenticate fine, but when l try to access any of the machines within
my network at work, l get the blue screen of death with the following
message (it's only shown for a second so l hope l got it right)
"DRIVER_IRQL_NOT_LESS_THAN".
It happens every single time l use it, and only when using the AT&T cable
line here at my inlaws house.
Is there any way l can work around it? Does anyone know of another ISP
around Kensington, New Hampshire that does not block VPN use?
Thanks in advance,
Alan
