tailscale: does not work as it can not find iptables in $PATH
Maintainer: @kesslerm @BKPepe
Environment: OpenWrt version: 22.03.0 / Target: ipq40xx/generic / ARCH: arm_cortex-a7_neon-vfpv4
Description:
I updated the OpenWRT to version 22.03.0 and install tailscale. After rebooting I tried running tailscale up and got the error that iptables can not be found in path. I assume this has something to do with the change to nftables, howevert I am not sure. I am also willing to help to solve the issue.

Would be nice to have them support nft also (please someone open a feature request on tails ale tracker)
Please see https://github.com/tailscale/tailscale/issues/4638 and https://github.com/tailscale/tailscale/issues/391 .
opkg install iptables-nft is the interim solution/requirement https://openwrt.org/docs/guide-user/services/vpn/tailscale/start
@kaikikokuke did you follow the OpenWrt Tailscale Guide. Specifically did you start tailscale with '--netfilter-mode=off'? 'nft' should already be installed on 22.03.
