Just putting this out there for anyone else that might stumble across this thread. It's an issue on at least Debian (and it's derivatives like Ubuntu) that supposedly has been addressed upstream, but has yet to make it into the downstream packages. The workaround is to run this command as root..
$ echo 64 > /proc/sys/net/ipv6/conf/eth0/hop_limit The catch is that only works until a reboot or the interface is restarted or unplugged. -- Christopher Tyler MTCRE/MTCNA/MTCTCE/MTCWE Total Highspeed Internet Services 417.851.1107 ----- Original Message ----- From: "Christopher Tyler" <[email protected]> To: "Mikrotik discussions" <[email protected]> Sent: Wednesday, July 15, 2015 1:56:36 PM Subject: Re: [Mikrotik] HE Tunnel Broker Setup Tried on my MAC and it works fine.

That is normal for some OS. Specifically, Linux will do that every time (or has with my RedHat varieties).

This will verify the routing from the PC toward the internet. If it works, then the problem is not in your PC.

I am guessing that 2001:470: router is the other end of the tunnel at HE. If that is the case, you should be able to ping that address as well. > > $ /sbin/ifconfig eth0 > > inet addr:X.X.X.X Bcast:X.X.X.X Mask:255.255.255.248 > > inet6 addr: fe80::4216:7eff:fead:286c/64 Scope:Link > > inet6 addr: 2001:470:XXXX:1:4216:7eff:fead:286c/64 Scope:Global > > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > > RX packets:323016851 errors:5 dropped:0 overruns:0 frame:4 > > TX packets:100741665 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:1000 > > RX bytes:468908409946 (436.7 GiB) TX bytes:10871913606 (10.1 GiB) > > Interrupt:20 Memory:f4100000-f4120000 > > > > $ ip -6 route show > > 2001:470:XXXX:1::/64 dev eth0 proto ra metric 1 > > fe80::/64 dev eth0 proto kernel metric 256 > > default via fe80::4e5e:cff:fe03:25d5 dev eth0 proto static metric > > 1024 This all looks right. -- Butch Evans Training and Support for WISPs 702-537-0979 http://store.wispgear.net/ http://www.butchevans.com/ _______________________________________________ Mikrotik mailing list [email protected] http://mail.butchevans.com/mailman/listinfo/mikrotik Visit http://blog.butchevans.com/ for tutorials related to Mikrotik RouterOS _______________________________________________ Mikrotik mailing list [email protected] http://mail.butchevans.com/mailman/listinfo/mikrotik Visit http://blog.butchevans.com/ for tutorials related to Mikrotik RouterOS _______________________________________________ Mikrotik mailing list [email protected] http://mail.butchevans.com/mailman/listinfo/mikrotik Visit http://blog.butchevans.com/ for tutorials related to Mikrotik RouterOS _______________________________________________ Mikrotik mailing list [email protected] http://mail.butchevans.com/mailman/listinfo/mikrotik Visit http://blog.butchevans.com/ for tutorials related to Mikrotik RouterOS
