Hi all,
When I add an ip address to an interface in OpenBSD 5.6 it will create
two routes:
172.16/16 link#15 UC 0 0 - 4
vether99
172.16.25.1 fe:e1:ba:d1:50:44 UHLl 0 0 - 1
lo0
before it would only create:
172.16/16 link#15 UC 0 0 - 4 vether99
New behaviour since 5.6? Oke
My problem:
`ping6 fe80::200:24ff:fecd:7df8%pppoe0` with pf disabled is no problem.
ping6, with pf enabled and 'set skip on lo0' does not work very well:
--- fe80::200:24ff:fecd:7df8%pppoe0 ping6 statistics ---
58 packets transmitted, 3 packets received, 94.8% packet loss
round-trip min/avg/max/std-dev = 0.320/0.393/0.491/0.072 ms
pf enabled and 'set skip on lo0' NOT set; works perfectly fine.
A situation:
'set skip on lo0' is set. ping6 is running.
I remove 'set skip on lo0' and enable the change with pfctl:

16 bytes from fe80::200:24ff:fecd:7df8%pppoe0, icmp_seq=117 hlim=64

The first two ping replies are the 3,2% that were working. After the
'No route to host' messages, ping starts responding normally.
I have seen no trouble with IPv4.
