This update adds new relay integration for NetBird clients. The new relay is based on web sockets and listens on a single port.
- Adds new relay implementation with websocket with single port relaying mechanism
- refactor peer connection logic, allowing upgrade and downgrade from/to P2P connection
- peer connections are faster since it connects first to relay and then upgrades to P2P
- maintains compatibility with old clients by not using the new relay
- updates infrastructure scripts with new relay service
The peer IP allocation logic was allocating sequential peer IP from the 100.64.0.0/10
address block.
Each account is created with a random subnet from 100.64.0.0/10.
The total amount of potential subnets is 64.
The new logic allocates random peer IP
from the account subnet.
This gives us flexibility to add support for
multi subnet accounts without overlapping IPs.
