I use Dynamic rulesets with IPFW: ipfw add check-state ipfw add deny tcp from any to any established ipfw add allow tcp from my-net to any setup keep-state But I also have services I need anyone on the net to get to, without me making a connection first from " my-net ". I allow such services with: allow tcp from any to my-net 25,80,443 setup in via xl0 keep-state This works fine for 25,80, and 443. However, when I apply the same rule for SSH, and login to my box remotely, about 10 minutes later, the connection just dies, and it dies with every connection. Removing the keep-state option for ssh effectively closes 22 obviously. Would check-state be a better option here?
