Thank you for reporting it here!
I would like to clarify some details to commit the fixes if necessary.
Firewall configuration (as a part of NGCP) has been introduced in
mr5.2.1, while Anthony's initial report was about upgrade
Did you experience described problem after upgrade on mr5.2.1 or after
upgrade on mr5.3.1 ?
Also as for upgrade on mr5.2.1 we were tried to make zero harm
as security->firewall->enable=no by default.
I would really appreciate detailed description here (private email if
you want). I would like to prevent this for other spce@ users.
