Hi, wonder if the wisdom of crowds can help us
We have an issue with people connecting to our FMS app.

What we’re using:
- Flash Remoting via an http gateway service

On client’s internal networks, the connection to the Flash Remoting gateway service on our server is not able to be established and times out.

Possible problems:
- Port being blocked
- Firewall preventing 2-way communication
- Windows firewall preventing communications
- Automatic routing for port 80 preventing the server response from reaching our app
- ??

Has anyone else run into this problem, any fixes or work arounds.
Thanks for your time and energy
