Problem: Bought a new AC86U router and set up IPv6 6in4 tunnel using Hurricane Electric tunnel broker as described in the wiki. But when I enable tunnel by updating my dynamic IP address to the tunnel service, most of the connections to the sites fail after timeout. Ping to the both IPv6 and IPv4 sites is ok.
I thought that it might be MTU issue. I've tried to determine it and played with different values in the IPv6 page settings and in tunnel setting on the HE site. Problem exists even with the minimum value of 1280 bytes. And, of course, test at http://test-ipv6.com completely fails, as it no ipv6 is configured on my machine.
On my previous router (AC66U) the same tunnel, with the same settings works perfectly. All tests at test-ipv6.com are passed and sites open without any problems. MTU is configured to 1480.
AC86U Firmware 384.5
AC66U Firmware 380.70
Any ideas?
