A simple rendezvous protocol implementation to help NAT traversal or hole punching.
Golang implementation for rndz.
- Simple and lightweight implementation
- Supports both TCP and UDP protocols
- Easy to integrate with existing Go projects
To install rndz-go, use go get:
go get github.com/optman/rndz-goHere's how you can use rndz-go to perform NAT traversal or hole punching.
import (
"context"
"net/netip"
"github.com/optman/rndz-go/client/tcp"
)
func main() {
rndzServer := "your-rendezvous-server"
c := tcp.NewClient(rndzServer, "c1", netip.AddrPort{})
defer c.Close()
l, _ := c.Listen(context.Background())
defer l.Close()
for {
conn, _ := l.Accept()
defer conn.Close()
// Handle connection
}
}import (

func main() {
rndzServer := "your-rendezvous-server"
c := tcp.NewClient(rndzServer, "c2", netip.AddrPort{})
defer c.Close()
conn, _ := c.Connect(context.Background(), "c1")
defer conn.Close()
// Use connection
}import (
"net/netip"

func main() {
rndzServer := "your-rendezvous-server"
id := "your-client-id"
c := udp.NewClient(rndzServer, id, netip.AddrPort{})
// Use client
