We have an external party, who wants to acces one of our citrix servers
behind the Bordermanager.
I created a new statefull filter for this company allowing incoming
traffic from their IP to our Citrix server at over port 1494.

My guess was that they would enter the address in their Citrix
client ant create a route in their firewall sending all traffic for to our Bordermanager. That should work, shouldn't it ?

But they want me to route ALL traffic for port 1494 to on our
Bordermanager, which offcourse is impossible because we have other traffic
coming in on port 1494 to a different citrix server.

What would be the best solution here ? Are there any other possibilities ?
(besides VPN, because that clashes with there intranet)

With kind regards,
