Hello,
I'm having IPv6 issues between Charter 6rd and Digital Ocean IPv6
servers. HTTP/HTTPS requests do not finish; perhaps MTU issues? Requests
to these destinations seem to work fine from some other places I have
IPv6 access such as a Vultr VPS. I can access the rest of the IPv6
internet without issue.
Source Subnet: 2602:100::/28 (Charter 6rd IPv6 service)
Source IP: 2602:100:4475:7e4e::1
Destination IP example 1: 2a03:b0c0:2:d0::1af:a001
Destination IP example 2: 2a01:4f8:210:31fd:1::5
Destination Subnet: 2a00::/12
Both of those example destinations are hosted at Digital Ocean.
It just hangs indefinitely for both of these:
