Testing flash file

Need help to solve a problem with a flash file which will not play on another IP subnet in either a wireless LAN or Ethernet LAN, both wireless and Ethernet network’s at different locations use IP addresses on different subnets, rather than being on the same source private IP address subnet, on the wireless latency is 5 to 20ms CPE’s to core address, either network have no problems with playing other flash files, is there some way I can analyse this file as the IT Dept. at the server location have said it plays no problem at their end ,

Below is screen shots of FlashA is two flash connections established, the 193.1.98.45 is the problem one which is OK near the core but on flashB is a CPE after connecting to this website and flashC is when selecting flash file no connection on port 1935 is established with that flash file but ok on the other test flash file, any advice is most welcome on this
