>Description:
On FreeBSD 4.3-STABLE, I could perform the following ipfw rules without problem.

208.141.46.11 is the actual interface, not a virutal IP. 208.141.46.249 is a aliased IP. The actual problem is, in fact, identd not working. 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 can't seem to find a problem.



$fwcmd add permit ip from 208.141.46.249 to any gid ancient
$fwcmd add permit ip from 208.141.46.11 to any gid ancient
$fwcmd add permit ip from any to any uid nobody
$fwcmd add permit ip from any to any uid root
$fwcmd add deny log ip from 208.141.46.249 to any
