For some reason ICQ is sending UDP packets every 30 seconds to a PC On my internal lan. I have been doing some reading up on IPF and just want some verification on a rule. I have already opened up the firewall to one IP address of thiers, but they obviously have more than one server. In order not to have to manually put in IP addresses of every server that is coming though I was wondering if I could put in the following rule: pass in quick on xl0 from 205.188.153.97/24 port = 4000 to any Would this let me allow (or block since it's getting blocked already) anything from them from port 4000 on thier end? I have played with other varients of rules and have gotten everything else I want don, done with IPF. But this is the only one that has stumped me. I am running 4.4 stable. I havn't compiled in the new IPF changes yet. Can someone quick give a look at that rule and tell me if it will work or not, or offer any other suggestions?
