Main mode doesn't work

[tracer]

My tunnel problem between 2.1.5 and 2.2 turned out to be a problem of Main mode.
I switched bach to two 2.1.5 pfsenses.
And had the same problems until I swicthed back to aggressive mode.

What do I need to change when I switch to Main mode ?

Can you share the generated config on /var/etc/ipsec/ipsec.conf and the /var/etc/ipsec/racoon.conf from machines?
