OPNsense firewall
Tipps und Tricks zur Einrichtung
A. Wie einrichten als VM
Post unter https://forum.opnsense.org/index.php?topic=2364.0
Assuming you don't have an Exterprise Plus licence then you're left with using the standard vSwitch. Create two of those and attach your NICs to them - if this is a home LAN then one NIC on each of the switches should do. Create the OPNsense VM with two NICs, connect one of those NICs to the 'WAN' vSwitch and the other to the 'LAN' vSwitch. Install OPNsense and configure it to your requirements, when it's up and running you should have a working firewall and LAN connection.
Nothing in my environment is directly connected to the internet (excpet the ESXi NICs) and everything (including the ESXi host) is routed throiugh OPNsense. Create any required VMs with single NICs (you don't really need more) and connect them to the LAN vSwitch and that should give you a quick and simple set-up, the beauty is you can rearrange things later should you desire to do so.
B. Verbindung mit einem lokalen LAN hinter OPNsense
Szenario:
Internet <-> Fritzbox <- quasi-DMZ -> OPNsense <-> LAN
Verbindung zwischen LAN und quasi-DMZ wollte nicht funktionieren - Zugriff auf Fritzbox war nicht möglich...
