Switch to FW4 (nft), check thread for another option?

I was able to fix this error by installing the package iptables-nft. I think this should be added as a dependency to the openwrt package.
Regardless, there are still some bugs from the tailscale team https://github.com/tailscale/tailscale/issues/4086#issuecomment-1243552689.
