I have a CCR1009-7G-1C-1S+ router with HE IPv6 tunnel. Ping6 works fine, but seemingly nothing else.
Do you have any idea what could be the problem? I could setup successfully HE tunnel in my other flat.
Full router config can be found here: https://gist.github.com/halacs/7194ff37 ... e7ffbfe73e
ICMPv6 is allowed in IPv6 firewall.
I have read that HTTPS issues usually happens in case of wrong MTU settings so this was my first suspect. Previously I had IPv4 MTU issues causing HTTPS connection problems, but I have solved it before.
Might useful info:
- HE tunnel MTU is 1280.
- I have a EoIP tunnel between my two flats. IPv6 works fine in flat "B" but in flat "A".
- I have PPPoE internet connection in flat "A" where IPv6 problem happens. PPPoE MTU is 1480 and I couldn't set higher.
