I’ve set up Tailscale with a custom exit node on
OpenWrt 21.02-SNAPSHOT r16399+159-c67509efd7 / LuCI openwrt-22.03 branch git-21.284.67084-e4d24f0,
firmware version 4.4.6.
Additionally, I followed the documentation on https://openwrt.org/docs/guide-user/services/vpn/tailscale/start to configure an additional interface and firewall settings. The steps I followed include:
- Creating a new unmanaged interface via LuCI.
- Adding a new firewall zone through Network → Firewall → Zones → Add in LuCI.
Setup Tailscale with custom exit node :
TailScale configuration
However, after setting everything up as shown, I noticed that my Tailscale connection is disconnecting and reconnecting. Below are the logs:

The problem with the disconnection and reconnection seems to occur when I add the new interface to the router through the LuCI portal. However, there are moments when connected that I am able to reach my exit node IP, so it seems to be working, but something is missing.
When I don’t create these interfaces and firewall rules, I don’t have an internet connection.
Could you advise me on what I might be missing?
