After the revamp of IPFW support in SSHGuard it took me a while to figure out why it wasn’t guarding anything anymore and then how to fix it. After some time I found out I had two identical rules (but different numbers). Then it took me again a while to figure out where the other rule was coming from, before I found it at the end of /usr/local/etc/rc.d/sshguard. Now it isn't there anymore.
Of course I could be just dreaming, because I don’t have any evidence. I love my FreeBSD boxes because I can get away with so little maintenance. Someone could argue I am neglecting them. That’s why I am only fixing things afterwards, when something gets broken.
My setup is working fine again. I just would like to help others who are setting up SSHGuard for the first time. It would have saved me some headscratching if something like 'ipfw "add 55000 deny ip from table(22) to me”’ would be set up as an example in the startup script - even if it was commented out. It could also be at the beginning, in the section "Add the following lines to /etc/rc.conf to enable sshguard” where it would also make sense.
