Hi again I spotted the following while my ISP disconnected my pppoe link last night.
I have the following /etc/hostname.pppoe0 file: inet 0.0.0.0 255.255.255.255 NONE \ pppoedev vlan35 \ authproto pap \ authname "<user>@vo.lu" \ authkey "<password>" dest 0.0.0.1 inet6 autoconf !/sbin/route add 0.0.0.0/0 -ifp pppoe0 0.0.0.1 !/sbin/route add ::/0 -ifp pppoe0 fe80:: As you can see, it get my IPv6 address trough autoconfiguration. After my pppoe reconnected again, I saw the following in ifconfig: pppoe0: flags=208851<UP,POINTOPOINT,RUNNING,SIMPLEX,MULTICAST,AUTOCONF6> mtu 1492 priority: 0 dev: vlan35 state: session sid: 0x44e PADI retries: 8 PADR retries: 0 time: 13:20:45 sppp: phase network authproto pap authname "<user>@vo.lu" groups: pppoe egress status: active inet6 fe80::XX:XX:XX:6c3a%pppoe0 -> prefixlen 64 scopeid 0x8 inet6 2001:XX:XX:6f3:XX:XX:XX:6c3a -> prefixlen 64 autoconf pltime 556434 vltime 2543634 inet6 2001:XX:XX:6f3:XX:XX:XX:9581 -> prefixlen 64 deprecated autoconf autoconfprivacy pltime 0 vltime 2990 inet6 2001:XX:XX:6f3:XX:XX:XX:80b4 -> prefixlen 64 deprecated autoconf autoconfprivacy pltime 0 vltime 88911 inet6 2001:XX:XX:6f3:XX:XX:XX:759e -> prefixlen 64 deprecated autoconf autoconfprivacy pltime 0 vltime 175252 inet6 2001:XX:XX:6f3:XX:XX:XX:348d -> prefixlen 64 deprecated autoconf autoconfprivacy pltime 0 vltime 261652 inet6 2001:XX:XX:6f3:XX:XX:XX:5b7e -> prefixlen 64 deprecated autoconf autoconfprivacy pltime 0 vltime 347933 inet6 2001:XX:XX:6f3:XX:XX:XX:a3be -> prefixlen 64 deprecated autoconf autoconfprivacy pltime 0 vltime 434046 inet6 2001:XX:XX:6f3:XX:XX:XX:87b2 -> prefixlen 64 autoconf autoconfprivacy pltime 1835 vltime 520374 inet 85.XX.XX.XX --> 80.XX.XX.XX netmask 0xffffffff inet6 2001:XX:XX:7c5:XX:XX:XX:6c3a -> prefixlen 64 autoconf pltime 604755 vltime 2591955 inet6 2001:XX:XX:7c5:XX:XX:XX:30c -> prefixlen 64 autoconf autoconfprivacy pltime 37915 vltime 556755 I got the new 2001:XX:XX:7c5::/64 prefix after the reconnect and OpenBSD added it to my interface. But it didn't remove the now invalid and no longer working 2001:XX:XX:6f3::/64 prefix addresses which caused quite some issues as my NAT was still using that address for part of the connections. Shouldn't those be removed as soon as their prefix is no longer valid? Or at least all be deprecated? Daniel -- Unix _IS_ user friendly - it's just selective about who its friends are!
