Firewall Wizards: RE: Application requires VPN - How are these handled?

["Melson, Paul" <PMelson () sequoianet com>]

It's certainly a valid point.  Trust (or untrust) should be a two-way model, and I don't see why you should trust what 
will or won't be allowed from their network to yours.  Ideally, you would want to terminate this tunnel at a point 
where you can then control packet and application data with a firewall of some type.  Never underestimate the power of 
the almighty dollar - if this is to accommodate a service you pay for, don't be afraid to ask for a solution that meets 
with your organization's security policies.  Only the biggest (and most foolish) vendors will let a services customer 
slip away over something this relatively small.

In the event that they don't budge and you don't have other options, a DMZ or other untrusted segment is an OK way to 
go.  You may also consider a personal firewall for the workstation.
