Hi, the fe80: range is a bit strange as it configured on not only one network interface on the same device. fe80:: is link local. When you are pinging to an fe80::-address, it is unclear where to route the packets to, as there mostly more than one fe80:: network as mentioned before.
Your "ping -6 -I pppoe-wan" works. "ping -6 fe80::0230:88ff:fe04:63d4%pppoe-wan" should work, too. This is the standard notation for link-local target addresses with the interface. regards Am Friday, den 9 October hub Emmanuel Blot folgendes in die Tasten: > Hi, > > I'm desperately trying to set up an IPv6 link to my ISP.
