Brian,


So, is there any scope for a generic UDP echo process that would allow
PMTUD without ICMP messages? It's probably easier to get a port open
in firewalls for that than to reverse the trend of ICMP filtering, as
long as the echo process has adequate DoS resistance.


I would hope that we could at least ping. Or, is that
off the table as well?


If you mean ICMP echo that seems to be blocked in many places.
