This setup runs the service as root, if you don't want to do this that is fine however you will need to run some commands here prefixed with sudo .

This will cause all the traffic from the host to be routed through the tunnel.

Login as Root on the Host you want to host Lavalink in

sudo -i
# or
ssh root@...

Run to enabled IP Non local bind (Now and permanently after reboot)

sysctl -w net.ipv6.ip_nonlocal_bind=1

echo 'net.ipv6.ip_nonlocal_bind = 1' >> /etc/sysctl.conf

Create the Lavalink directory

mkdir -p /root/lavalink

Get a IPV6 /48 block assigned to you from https://tunnelbroker.net

• Once you created the tunnel and assigned an /48 block to it go to "Advanced" and copy the "Example Update URL:"

Create the Tunnel IP updater script

nano /root/lavalink/tunnel_ip_updater.sh

Contents of tunnel_ip_updater.sh

#!/bin/sh

curl -4 <Example Update URL>

Create the Tunnel Startup script

nano /root/lavalink/network.sh

Contents of network.sh

• When prompted for the <IP BLOCK>, If your assigned IP block is 2005:258:bf28::/48 your <IP BLOCK> will be 2005:258:bf28::2/48

#!/bin/sh
# If your host is behind a NAT then you will need to use the NAT IPv4 here
# If your host is not behind a NAT, then you will use the public IPv4 of the host.

ip tunnel add  <TunnelName> mode sit remote <Tunnel Server IPv4> local <Host IPv4/NAT IPv4> ttl 255 || ip tunnel change <TunnelName> mode sit remote <Tunnel Server IPv4> local <Host IPv4/NAT IPv4> ttl 25
ip link set <TunnelName> up
ip addr replace <IP BLOCK> dev <TunnelName>
ip route replace ::/0 dev <TunnelName>
ip -6 route replace local <IP BLOCK> dev l
