- Update tailscale to version 1.36.0 - Patch iptables support Tailscale does not (yet) support nftables. Tailscale allows running with --netfilter=off allowing end-user to create his own firewall rules, but this affects only tailscale cli, not tailscaled daemon, so connection cannot be made without error telling that tailscaled was unable to determine execute iptables for determining it's version. There is a work-around for those who do not want nft-iptables compatibility package; they can create a script to /usr/bin/iptables which responds to --version argument and echos fake version string and on any other arguments or no arguments, just exits. After this procedure and starting tailscale cli with netfilter off- it works. Openwrt has moved on to nftables, so iptables manipulation seems unnecessary. Especially for other reasons, on Openwrt, firewall should be configured on it's own, because firewall rules made by other software, such as tailscale, loose their firewalling rules when firewall restarts. So I patched it to allow "fake" iptables pointing to executable /bin/false and ignoring version request. And I also set cli to default to netfilter off setting. If still end-user wants to use iptables, this patch does not make it impossible; just install iptables, or nft-iptables, and run tailscale with argument --netfilter=on and it works out as it did before, tailscaled daemon still matches with iptables if it is found in $PATH.

Tailscale
This readme should help you with tailscale client setup.
Install
There are two packages related to tailscale. Tailscaled (daemon which has to run every time you want to be connected to VPN) and tailscale (package with a utility which is necessary for registering device).
To install them run
opkg install tailscale tailscaled
First setup
First, enable and run daemon
/etc/init.d/tailscale enable
/etc/init.d/tailscale start
Then you should use tailscale utility to get a login link for your device.
Run command and finish device registration with the given URL.
tailscale up
If you are running with nftables, it is not supported by tailscale, so disable it and configure firewall by yourself and add argument --netfilter-mode off to tailscale up command to disable iptables use.
After that, you should see your router in tailscale admin page.
