1 year ago local tun-mtu is 1500, strangely
on the server, we get similar messages with different values.
Maybe some of these can be silenced, if not, these are probably all spurious.
Hard to find solutions other than "make client and server match". Maybe the server needs to specify also?

these don't seem to cause problems but the server logs are too crowded
these are from /var/log/messages on futel-prod
