Some moron is blocking ICMP on your network. You have a workaround
(iptables can clamp the MSS), not a fix.

No need for beer. Instead do me — and the whole world — a favour by
finding out where and why ICMP is blocked, and fixing it.

A little percussive education is sometimes needed, but it's worth it to
stop this brain damage from spreading ☺
