    Outbound Ports.

    I am running Redhat Linux on my server.

    What i want to do is disable all outbound ports exept the ones i chose to. Please recomend me some firewall or script that would best optimise my requirements.

    Would KISS or APF do that job for me ?

    Thanks in advance

    APF works good.

    APF

    I'd recommend APF for that.

    I tried APF. Now something wrong's going on. When i enable APF I cant access any port on the outside. And my screen is getting flooded with these kind of errors..
