Issues connecting with Cable modem

[rage290]

I have COD UO running on Win 2003 server, and I only have one issue. I have alot of people on Cable modem that can't connect to my server. Everyone on DSL/T1 etc. have no problems connecting and playing. The server is running on a DSL connection with good bandwidth. But, for some reason, when people with Cable modems try to connect, it hangs on the "Awaiting Gamestate" message. I can see them hitting the server, but they never get past that point. My DSL friends connect without a problem, and generally get a ping less than 50. There is no lag or any other problems besides this. Has anyone seen this before, or does anyone know what might be happening?

Make sure the client has connection settings in multiplayer options set to lan/cable we had a similar problem where this wasn't set and pings where high and kept getting kicked. This in my only suggestion.
