Port Ranges Don't Work

[bspiller]

I added the following port ranges to my CSF install and they don't work. Some people can't connect to the Ventrilo/TeamSpeak servers behind these port ranges 3000:4207,8767:8779. It's my understanding adding a port range allows all the ports withing that range to be opened so why am I having issues with people connecting? If I disable CSF players can connect with no issues. The Port ranges are added in the following fields:

TCP_IN
TCP_OUT
UDP_IN
UDP_OUT

While I place some hope in this company, I don't think I'll get any response or resolution

CSF 6.21 (Latest Updates On)
CentOS 6.4

That would suggest that you haven't opened up ports that you need. Check /var/log/messages when connecting for Firewall messages from the kernel to see which ones have been missed.

I'm getting a lot of DPT=6000 from my VOIP servers. That would be the port to open right?

Also what is the SPT=

Yes, you are right DPT = Destination PorT, and you need to add it to your CSF allow ports

On the other hand SPT = Source PorT.

Sounds good. After adding 6000 to UDP everything works good.
