Site-to-Site Networking
You have two or more offices (or a home and an office) and want their local networks to communicate as if they were on the same LAN — without installing Rabtly on every single device at each site.
The problem
Linking whole networks usually means configuring site-to-site IPsec tunnels on routers: matching parameters on both ends, static IPs, and fragile rekeying. Adding a third site means reconfiguring the others.
How Rabtly helps
- One device bridges a whole subnet — a single Rabtly node at each site advertises its local network, so the others can reach every device on it.
- No per-device install — printers, NAS boxes, and legacy gear stay untouched; the subnet router handles routing for them.
- Add a site in minutes — bring up one more relay node, advertise its routes, and the mesh expands.
How it works
Place one Rabtly node per site
Install the daemon on a machine at each site that can see the local LAN (a small server or always-on box).
Advertise each site’s subnet
Bring the node up advertising its local CIDR, e.g. rabtly up --advertise-routes 192.168.1.0/24. Approve the routes in the dashboard.
Sites see each other
Each site can now reach the others’ advertised subnets directly. Add a third site by repeating the same two steps.
