Block all ports / traffic execpt for one port


I have recently setup a proxy, and hence need all ports blocked apart from port 222 (proxy port)

I have tried with the rules manager, but, they dont appear to work, can anyone give some advice please?

Not sure what you’re asking. You want to block all traffic in not from port 222, or block all traffic out not to port 222?

You said the rules don’t appear to work? What doesn’t seem to work?

This may be of help
