Changed the subject... Anyone have any thoughts on terminal sessions
coming in through ISA? And associated risks?

Thanks.

Well to gget around this problem, i published a workstation terminal to
the internet.

Works great from behind the other firewall... now how much of a security
risk might this be? Are the user/pass encrypted when logging in?

I've had this happen when GRE is not allowed back to the client.

Users are behind a Netopia router that support basic packet filtering
and it
doesn't allow GRE back to the client.

BTW it seems to connect then does verifying user and password then craps
out with a 721 error (something about ppp not supported).

It is a default client setup except I have the 'include domain' checked
so I can input my domain name and I unchecked require encryption just in
case.

Thanks.

I am trying to create a vpn connection to my isa network from a client
inside another network (behind a pix firewall).

The isa server seems to allow a vpn to standard internet clients...

Any thoughts on this?

Thanks...
