Router: Ubiquiti USG-3P configured as Exit Node
OpenWrt v24.10.0, r28427-6df0e3d02a

There is a problem with Tailscale Exit Node:

1 Log files are filling up
2 Running a Speed Test shows the speed is being rate limited and I loose access to the console.

Thanks for your response.

It looks very much like this issue https://github.com/tailscale/tailscale/issues/11565

The reduced Internet Speed performance of Down/Up: 8.35 Mbps / 8.21 Mbps maybe due to the CPU of the USG-3P. Running the same test on the ER-4 running EdgeOS, faster CPU and more memory produces better results.
