Symptom. On reboot, connectivity was lost with Drake network.
This machine has an ethernet card connected directly to that network, so no routing is configured.
Fixed by ip route add 172.27.27.0/24 via 172.27.27.1.
Plan is to add this route through Salt for every machine on Intranought, and via $IP_GATEWAY for tunnels, but that one is probably already configured.
We also need to ensure other servers are OK, and so provide a solution for:
- FreeBSD
- Debian
- RHEL / CentOS / Rocky
