In 1.3.6, the following is valid and works:-
set policy route tcp-mss-adjust-1436 rule 10 protocol 'tcp' set policy route tcp-mss-adjust-1436 rule 10 set tcp-mss '1436' set policy route tcp-mss-adjust-1436 rule 10 tcp flags 'SYN' set interfaces ethernet eth0 vif 666 policy route 'tcp-mss-adjust-1436'
However in 1.4.0-epa1, the flags have to be represented in lower case, for example:-
set policy route tcp-mss-adjust-1436 rule 10 tcp flags syn
Doing a migration from 1.3.6 to 1.4.0-epa1 containing such config makes a bit of a mess:-
{F4222630}
I think the migration script needs to change the case of the flags in such config.
