OK Smartass...:)
Go get a Linksys and see if you can get pptp through it "without" udp 500. They
seem to use it no matter that it's ipsec.

PPTP not use IPSec NAT-T, yanumptie...
Many NAT-based devices trash otherwise functional PPTP traffic.
If you get a network capture of the traffic at both sides of the "router", we
can examineit or the common failure point (PeerID gets changed somewhere along
the line).

Hello,
I have a point to point VPN setup with ISA2006. This has been working just fine
until my Internet Router Died. I have a new router on order but I have a
question.
I put a new router (one I had around) in place of my dead router. On this
router (Linksys befsx41) I enabled VPN pass through. If I plug a laptop into
the BEFSX41 directly I can start a PPTP connection and connect to the remote
ISA2006 server.
However if I try to start the point to point PPTP connection between the Local
ISA2006 server and the Remote ISA 2006 server I get the following error message
from the routing and remote access service:
An error occurred during connection of the interface. The connection was
terminated by the remote computer before it could be completed. For further
assistance click More Info or search Help and Support Center for this error
number.
However there is no error number.
If I connect my ISA server directly to my broadband connection then the Tunnel
works fine (that is ISA to ISA without the intervening router). Now before
someone jumps to conclusions about why I have the router, I am on a dynamic IP
address at home where I am connecting from and I want ISA to always have a
fixed address. In addition I have two Internet connections one Cable and one
DSL and the Router (Linksys RV042) handles connection to both and provides
failover and bandwidth aggregation. It also provides some simple packet
filtering that cuts down on a lot of the BS that in on the broadbands.
The VPN works fine with the RV042 but not with the older BEFSX41 and I would
like to understand why, especially since a VPN connection to the same remote
ISA server works fine when connecting from a laptop that is connected to same
Router.
Thanks
Bill
