When I set this type of firewall ruleset up on the older versions, identd was running out of inetd.conf, as user root. I could be able to force users not to abuse my hosts, and still permit identd to work for me. As of 4.4-RELEASE/4.5-RC, this same setup causes identd to stop working. I don't know what has changed since then, I was browsing the CVS archive, and I ca n't seem to find a problem.
