hi
i did the carp ip loadbalancing setup as describe at the man page.
i did it on an full funktional carp cluster that means that carp an pf is ok.
host A:
inet 10.100.0.254 255.255.252.0 10.100.3.255 carpdev em0 vhid 25 pass office2world link0 link1 group lan_if

inet alias 10.100.1.253 255.255.252.0 NONE
inet 10.100.0.254 255.255.252.0 10.100.3.255 carpdev em0 vhid 26 pass office2world advskew 100

inet alias 10.100.1.253 255.255.252.0 NONE
host B:

inet 10.100.0.254 255.255.252.0 10.100.3.255 carpdev em0 vhid 25 pass office2world advskew 100 link0 link1 group lan_if

inet alias 10.100.1.253 255.255.252.0 NONE
inet 10.100.0.254 255.255.252.0 10.100.3.255 carpdev em0 vhid 26 pass office2world

inet alias 10.100.1.253 255.255.252.0 NONE
after the changes some host are not able to reach the default gw 10.100.0.254 and some works fine.

i test this with my own system ( one freebsd , one linux ) both on the same switch / segment.
the freebsd system have 10.100.1.82 as ip the linux have 10.100.2.155 (by dhcp )
the freebsd works the linux don't .
is there an known issue ? maybee that carp ip loadblancing have problems with /22 networks ?
holger.
ps. sorry for my ugly english
