[isalist] Point to Point VPN ISA 2006

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
