Each DMZ VPC (`syd` 198.18.30.0/24, `mel` 198.18.31.0/24) holds a postfix edge host and a vpn host. The vpn
host runs wg0 as a /31 point-to-point link to its own prodnxsr0020 interface
(`wg-syd` on 51821, `wg-mel` on 51822; `router_links` output) and forwards the
lab routes for its VPC; the edge host reaches the lab through it and has no
WireGuard. Link /31s and vpn loopbacks (dum0) come from 198.18.2.160/27. Lab
WireGuard. The VPC /24 is connected on both hosts, so it wins over the lab
198.18.0.0/16 route via the vpn host. Link /31s and vpn loopbacks (dum0) come from 198.18.2.160/27. Lab
traffic is sourced from the /31 until Puppet brings up FRR, which peers OSPF
over wg0 and advertises the loopback and VPC to the router. Router keys live at `kv/service/wireguard/binarylane/prodnxsr0020-<region>`.
wg0 is bootstrapped from a key in `user_data` (readable via the BinaryLane
modules/binarylane/main.tf
