I get time-out errors when my clients try to visit a website which has IPv6 address. Some sites works, others doesnt. I want to trace the issue, but I'm not an expert. Maybe something could be wrong with my configuration.
Here's a wireshark. The 2a02:587 is my desktop, the other address is the site which I get time-out error on Chrome.
I believe it happend after ISP change. It's a hAP ac2, made a reset configuration and I set up only basic things. My config is:
getting a prefix /56 using dhcpv6 client from my isp, assigning a /64 to my bridge-lan and ND is on.
IPv6 firewall is off on routerboard and pc.
Could you help me trace this issue?
