Well, with almost everybody using PPP0E in germany and at least half
of europe our mtu is somewhere arround 1480. Many routers are braindead
(ICMP lobotomiced).
When you hit somebody on an ip2ip link or IPv6 tunnel your mtu goes down
to even smaller packets and things live ftp or ssh simply break. I have
seen many gamers on mtu = 1024 and smaller.
Kind regards
