SDC with a Flex 6600

Hi.
I am new to UT4LW software and have just spent the afternoon setting up the SDC to provide spots. I think I have it configured correctly ( I am not an expert! ) but cannot get spots to show across the screen. I have a feeling that the problem is with the UDP port 4990. I set it according to a message I saw on here but am wondering if I have to get into the router and do the same there?
Any advice would be appreciated. I have registered and donated to Yuri.

Panic over!! I had the wrong IP address to connect to SDR. I can now see spots traversing the screen, although there are no call signs as yet!!
