I have a fairly vanilla OpenBSD 5.7 installation on a machine for which my provider told me,
Net : 5.28.62.155, 2001:41c9:1:41c::155 My pf.conf is simple; it still has the, block return # block stateless traffic that I suppose I got from somewhere and generally seems to work fine. I can ping 5.28.62.155 just fine from anywhere, and from on the machine itself I can ping6 its other address. I don't have IPv6 set up at home but from various online IPv6 ping check tools I /don't/ seem to be able to ping 2001:41c9:1:41c::155. On the machine "route show" provides a bunch of stuff, Internet6: Destination Gateway Flags Refs Use Mtu Prio Iface ::/104 localhost UGRS 0 0 32768 8 lo0 ::/96 localhost UGRS 0 0 32768 8 lo0 localhost localhost UHl 14 0 32768 1 lo0 localhost localhost UH 0 0 32768 4 lo0 ::127.0.0.0/104 localhost UGRS 0 0 32768 8 lo0 ::224.0.0.0/100 localhost UGRS 0 0 32768 8 lo0 ::255.0.0.0/104 localhost UGRS 0 0 32768 8 lo0 ::ffff:0.0.0.0/96 localhost UGRS 0 0 32768 8 lo0 2001-41c9-0001-041 link#1 UC 0 0 - 4 vio0 green.ixod.org fe:ff:00:00:4f:1a UHLl 0 22 - 1 lo0 2002::/24 localhost UGRS 0 0 32768 8 lo0 2002:7f00::/24 localhost UGRS 0 0 32768 8 lo0 2002:e000::/20 localhost UGRS 0 0 32768 8 lo0 2002:ff00::/24 localhost UGRS 0 0 32768 8 lo0 fe80::/10 localhost UGRS 0 0 32768 8 lo0 fe80::%vio0/64 link#1 UC 2 0 - 4 vio0 fe80::523d:e5ff:fe 50:3d:e5:3b:a1:3f UHLc 0 102 - 4 vio0 fe80::523d:e5ff:fe 50:3d:e5:3b:d7:3f UHLc 0 116 - 4 vio0 fe80::fcff:ff:fe00 fe:ff:00:00:4f:1a UHLl 0 0 - 1 lo0 fe80::%lo0/64 fe80::1%lo0 U 0 0 32768 4 lo0 fe80::1%lo0 fe80::1%lo0 UHl 0 0 32768 1 lo0 fec0::/10 localhost UGRS 0 0 32768 8 lo0 ff01::/16 localhost UGRS 0 0 32768 8 lo0 ff01::%vio0/32 link#1 UC 0 0 - 4 vio0 ff01::%lo0/32 localhost UC 0 0 32768 4 lo0 ff02::/16 localhost UGRS 0 0 32768 8 lo0 ff02::%vio0/32 link#1 UC 0 0 - 4 vio0 ff02::%lo0/32 localhost UC 0 0 32768 4 lo0 When I use one of the online ping6 tools, on tcpdump I can watch requests come in, like, 21:57:52.144975 2a02:348:82:cb69::6 > green.ixod.org: icmp6: echo request (id:3244 seq:0) [icmp6 cksum ok] (len 40, hlim 248) but I never seem to see anything go back out on the interface (and neither it seems do they). Should I do something else to make the machine pingable via IPv6? Feel free to just point me to the fine manual if I missed something, I'm still learning the places where documentation lurks. -- Mark
