[OpenWrt-Devel] 6in4 does not recover after wan outage
I'm testing BB rc3 on a Buffalo WBMR-HP-G300H and for the most part its working fine and I'm getting a rock solid ADSL connection with it. However I've noticed that if the ADSL line drops then when it recovers my SiXXS 6in4 tunnel does not automatically re-establish the connection. There doesn't seem to be any magic config values to set either in the LUCI interface or at http://wiki.openwrt.org/doc/uci/network#protocol.6in4.ipv6-in-ipv4.tunnel Is this a missing feature or is there a bug lurking somewhere in the new event mechanism? For reference I've got the following in my wan and wan6 configs (passwords and IP addresses suitably redacted). config interface 'wan' option _orig_ifname 'nas0' option _orig_bridge 'false' option proto 'pppoa' option encaps 'vc' option atmdev '0' option vci '38' option vpi '0' option username 'auser' option password 'apass' option mtu '1458' option peerdns '0' option dns 'x.x.x.x' config interface 'wan6' option _orig_ifname '@wan' option _orig_bridge 'false' option proto '6in4' option peeraddr 'y.y.y.y' option ip6addr 'a:b:c::d' option ip6prefix 'e:f::/48' I'm happy to help debug etc where needed and will log a trac ticket if it isn't down to my stupidity!

Hi Richard, could you please post the output of: ifstatus wan and ifstatus wan6 when said situation occurs? Cheers, Steven ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel

Sure. during, after and before situation included below. I anonymised
the IP addresses a little but tried to mark common prefixes just in case
it matters to you.

Incase you need it fixed now, here's a workaround.
Throw this in like /etc/hotplug.d/iface/99-6in4-fix.
Not tested, chopped down version of what I run for another reason.
The loop isn't 10 seconds. The failed ping takes about 7 seconds. So
this tests the wan int for about 1m30s.
#!/bin/sh
if [ $ACTION = ifup ] [ $INTERFACE = wan ]; then
fix6in4 () {
. /lib/functions/network.sh
network_get_device wanIF wan
loop=0
ping=/bin/ping -W 3 -c 5 -q -I $wanIF
until [ $loop -gt 10 ] || $ping 8.8.8.8 /dev/null 21; do
let loop++
sleep 1
done
if [ $loop -lt 11 ]; then ifup wan6
else /usr/bin/logger -t 6in4-fix -p user.notice Failed to
reset 6in4 tunnel.; fi
}
fix6in4
fi
