New to Opnsense and few questions

[meazz1]

I have been using Mikrotik and EdgeRouse os for my home need.
It's a very basic setup, pretty much out of the box configuration, default firewall setting with fasttrack in mikrotik .
Only thing i added is the port forwarding for my nextcloud app.

Installed Opnsense last night to play around and once I'm familiarize  myself little bit more, I will eventually replace my existing router.
Does  Opnsense enable default firewall after initial configuration or I need to create my own rules?
If it does not is there a wiki page?

The default acts like a home router. You have two pass rules which allow any traffic and SNAT for all outbound traffic. You should harden your configuration to get more security.
