Just had to increase the bandwidth limit and was successful for doing so on four stream but on one can't do. Get the followiong error:
Configuration could not be updated: The selected port number is in use; the next available port is 9900.

Not trying to change any port. Want to keep the same ports as it is,. onlu increase the limit. In firewall I have ports 9900 to 10000 open and stream in question is streaming at port 9998.
Any help will be much appreciated.
Thanks

I think the reason is becasue SHOUTcast v2 requires 5 ports.... 9998, 9999, 10000, 10001 & 10002 but since you can't go past 10000 so either lower the port or raise the limit (not sure if you can go over 10000 though)

You can use 10000+ but you are correct, he needs 4 (or 5) contiguous un-used ports to use.  I assume he is using Auto DJ, which uses the extra ports.

Opened ports in CSF firewall to 10005 and it is working.
