Define connection state in firewall

[wiryono]

Hi usually in firewall we can define connection state ( e.g iptables using -m conntrack --ctstate ) for NEW or ESTABLISHED

What is the equivalent option in opnsense. I find there is no option for this value, but there is state table in the Firewall > Diagnostics

AFAIK not available and not neccessary. ESTABLISHED (and RELATED) connections back are allowed by default. Do you have a use case for NEW?
