[Freeswitch-users] ICMP... and MTU

[Kristian Kielhofner]

Generally speaking various PMTU, ICMP, and MTU issues are a
significant problem.  My experience has been it's much worse with UDP
than TCP as broken and/or misconfigured devices seem to cause more
problems with UDP fragments than TCP fragments (which do generally
work).  I talk about this quite a bit here:

I've also see this mindset that blocking all ICMP will somehow make your network more secure, In doing this you're actually breaking PMTU and the internet in general.  So check your firewalls, if you're blocking repent now and fix it... Input and discussions would be welcome on this topic.
