Intermittent internet from Exit node

Hi Team,

I have been happily using Tailscale for quite sometime now. I have a use case implemented at home where I have a tailscale client installed on an OpenWRT router.

This router in turn connects to a tailscale exit node in another country running on raspberry pi. Everything works for a while and suddenly clients connected to the exit node lose internet. It will stop working and weirdly some sites like and works perfectly but all other general internet breaks.

Have tried multiple methods but doesn’t seems to work, even reset and ran the exit node again. Cant do a full reinstall as device is another country and tailscale is the only way to reach and manage it.

I know it has to be small fix a minor config am missing. Please help.
