You might be referring to http://www.freebsd.org/cgi/query-pr.cgi?pr=121574 which should have been fixed with rev 1.54 (MFC'ed in 1.52.2.1 to RELENG_7) of ip_carp.c > Am I doing something wrong?

Make sure that you are configuring the same aliases with the same netmasks on all members of the carp group - preferably before bringing the interface up for the first time (though it should properly recalculate the hashes as you add aliases). As you seem to be using pfsense you might want to check with them to make sure they have the fix in their build - though I recall it was a joined effort back then. -- /"\ Best regards, | mla...@freebsd.org \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | mla...@efnet / \ ASCII Ribbon Campaign | Against HTML Mail and News _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
