I have no idea what might be wrong. I have this ISP for a few years and on last weeks it stopped working.
I receive IPv4 and IPv6 from it using DHCP. Modem has been in bridge mode, I changed it back to router but got the same errors. But when I connect a laptop to it, it works fine, both in router and bridge modes.
ping gives 100% loss
# ping -c 4 -I eth2 v4.ipv6-test.com
PING v4.ipv6-test.com (51.75.78.103) from 192.168.20.16 eth2: 56(84) bytes of data.

Oddly, httping reports success
