I am trying to use OPNsense to use as a firewall for my servers. My idea is that I will statically set a public IP address to the server and a firewall through the servers. But as soon as I put it there, I automatically lose access to the Internet, don't you know how to teach OPnsense to let it go? Thank you
If the servers have public IP addresses you need to use OPNsense as a router and just create firewall rules without NAT.
