Hello,
there is no need to change canreinvite for provider configuration.
Do not change MTU. Probably there will be another problem. I expect
packet size 1466 would pass and higher will have the same result. It
would be interesting to make the same test from the outside towards
your asterisk with size 2 bytes larger the highest you are able to
ping.
