Block most ports

MagikMark

Is it recommended to block all ports that your network won't be needing?

Gertjan

When pf; the pfSEnse firewall, loads, for each interface it finds; the last rule will be a block all rule.
Up to you to declare a pass rule for traffic you want to pass, an extra last block rule is not needed.
You might want to do it anyway, as this will show the traffic it hits :

Do you mean outgoing connections?

You can allow only the ports you need. You will find there are a lot of ports you didn't realise you needed for most environments.
