Is MTU path discovery broken? I.e. IP packets bigger then MTU of the
tunnel do not pass. You can try to send ICMP packets with bigger and
bigger size while don't-fragment bit is set. You can use ping tool
for the tests.
I think is not a MTU problem, the MTU is same for all kernel I use
kernel 4.10.17 or previous
ping (ICMP): work
host (UDP) : work
ssh (TCP) : work
ftp (TCP) : work
smb (TCP) : work
kernel 4.11.3-200 and 4.11.3-201
ping (ICMP): work
host (UDP) : work
ssh (TCP) : NOT work
ftp (TCP) : NOT work
smb (TCP) : NOT work
I have fill a bugzilla:
