Hi,
When creating a NAT rule in OpnSense you can select things like, LAN net (ie the /24 network for lan for example in my case) or LAN address (ie the IP address of OpnSense on the LAN interface).
One definition I am unsure of is the option 'This Firewall'.
What address or range of addresses is this? If I am choosing a destination address of 'this firewall' where is it going? Or If I choose a source address of 'This Firewall' what Ip's are included in this definition.
I tried looking it up in the documentation but could not find an answer. Thank you in advance.
Pete
