Looked at the docs and they say it is possible to 1:1 NAT WAN to OPT
but that you will almost always do it to LAN.
I want to leave the LAN interface unused except for admin'ing the Monowall.
What steps are needed to configure a 1:1 NAT like so:
I'd like the OPT1 interface to get an IP address of 140.x.x.1 so that
hosts inside the OPT1 interface can use that as the default gateway.
Is proxyarp needed if 1:1 mapping an entire subnet?
Upstream of the monowall, 10.0.0.2 is the interface on the router.
