Routing & Reachability
Learn how anchors find each other, choose a route, and offer subnets and exit nodes.
- Discovery and NAT TraversalAn anchor finds its whole realm from one address and detects the type of NAT it is behind. It reaches each peer directly or through a relay.
- Routing and AddressesLearn how anchors choose a route to each peer, and how every anchor gets its addresses without any configuration.
- Load BalancingSeveral anchors that share one private IPv4 address act as one destination. Clients spread across them with no DNS, load balancer or gateway in front.
- Subnet Routers and ExitsA subnet router gives its realm access to a private network, and an exit node gives access to the internet. Clients spread their traffic across routers, flow by flow.
- Run ModesCompare the ways to run an anchor: interface, userspace, reverse proxy, uplink and low latency. Learn what each one gives the host, costs it and needs from it.
