I'm running AsusWRT Merlin v3004.388.11 on an RT-AX86U router and just updated tailscale to v1.96.1 on Entware. After the upgrade, tailscale seems to crash each time I try to turn it on, with the following error:
Doing a bit of troubleshooting with Gemini, it appears that turning tailscale on with the --netfilter-mode=off flag works and doesn't cause it to crash. Anybody else facing the same issue? Any suggestions?
