WAN

Internet access comes from LMI. The modem is connected through VDSL copper next to the Omni main electrical panels.

The modem is up in the rack area near saros (a desktop computer running Debian Stretch) which serves as the primary gateway router.

Our public IP is 142.254.26.9 aka room.sudoroom.org.
