ok, I finally set up the apf firewall with the ad plugin. I realized I can use it for inbound traffic without bothering with the outbound module...
nevertheless maybe someone can help me a little bit with outgoing traffic rules. basically all ports opened for incoming which send back data like 21,25,80,81,443 need to be opened but what about ftp? I thought that was flowing out through different ports?
can someone explain this auto resetting of rules after 5mins? what exactly happens after 5 min? if I make changes I have 5 mins to try them out afterwards they are reset? if I did not manage to try it out in 5 mins I just have to restart apf to get 5 more mins?
