port forwarding allows only one incoming connection

[thisisboni]

Hi:

I have a Belkin N1 wireless router - I have enabled port forwarding for a port that forwards it to a web server machine.
The issue is whenever a person gets on a connection of the application the application cannot be viewed by another person.
Not sure what the issue can be - any help will be much appreciated.
Please let me know if you need more information.

Thanks

Anyone ?!?

Also, just noticed that the problem occurs only when I have a connection open from within the network - it works fine from outside accepting multiple connections as long as no connections are open within the network.

Any help will be much appreciated.

Thanks
