Cisco VPNs and protocols

[pinion9]

I work in a hospital and I am trying to get a Radiologist set up with a client in his home. The client works properly when he brings his laptop in and is on the wire, but not through the Cisco VPN.

He is trying to query some images from a server. In the server I set up what port his request will come through. If he is coming through a VPN using tunneling protocol, will this change the port that the server sees?

On an established VPN connection (Cisco or not), the client should behave as if it's on the LAN and therefore, the port shouldn't change.

Although you may wanna explain more about that imaging server set up you have...normally in a client-server setup, the port that client uses is a random port number. So how could you have specified which port the client will be using to connect??

you probably need to enable "nat traversal" on the cisco concentrator. This forces clients to add a tcp or udp layer to the tunneled traffic.

without this option soho routers frequently "break" vpns.

This is speciality equipment for a Picture Archival and Communication System. In the client you specify which port to use, and on the server you enter the information (AETitle, Hostname, and port)
