Strongswan works fine for almost 3 years.
I have upgraded strongswan to version 5.6.3 in July 6.

Last week, I can not login email server with starttls on the other side of IPSec \
tunnel, and can not get a web page which size bigger than 1200byte. Finaly, I found \
setting MTU=1422, everything goes fine again.

Why this happen?
Do I have to set MUT lower than 1422?
