I see this issue referenced also in http://lists.freebsd.org/pipermail/freebsd-net/2008-March/017160.html and there are suggestions this is a known issue - however I still see it in FreeBSD 7.1 (pfSense 1.2.3-prerelease). I cannot find a PR on this, but my searching skills may be inadequate.. Am I doing something wrong? I tried assigning the alias with both /32 and /24 netmasks. /Eirik
