I wanted to create 3 Tailscale exit nodes for my 3 ISPs: Globe, PLDT, and Converge. I’m thinking of using it as a DIY VPN because sometimes some sites are slow on an ISP.
I mapped each VM to different VLAN specific to the ISP it will use.
Issue: Duplicate node key
I encountered an issue where when I clone a VM with running Tailscale, running tailscale up results in the same node key. To reset the node key, I had to:
apt-get remove tailscale
rm -r /var/cache/tailscale
rm /var/lib/tailscale/tailscaled.state
apt-get install tailscale
tailscale up -reset
