Well, PPPoE is a tunnel, but I guess that's splitting hairs.
But regardless, I had trouble this morning with Youtube that might be
related to the same issue.
One possible solution to force TCP MSS. For example on my FreeBSD
router at home i used PF's scrub rule for ipv6 tunnel to set
mss to 1220 bytes.
If you use PPPoE as underlying technology, decrease this vale little
bit more - 1212 or less.
Min MTU size allowable for ipv6 is 1280 according to RFC. Wouldn't
setting the MSS size to 1212 or 1220 essentially break that RFC as well
(1220+40 < 1280) or does the RFC only explicitly state the MTU has to be
at least 1280?
