Does anyone know what `first_i_p` represents in the `ips.json` dbag? I am
assuming it is the Source NAT IP, but I can't find it represented anywhere in
the code (other than in a test). If it does represent the Source NAT, then we
can use it to maintain the order and keep the Source NAT IP as the primary IP
on the Nic. That was the bug I was trying to fix in my #1741 PR.
Example with: 1) source nat 2) port forwarding 3) static nat 4) load
balancer
