iPhone needs to be pinged before it can access network via subnet router

Original post

I did some more investigation into my issue and it seems the issue is with my device, and not the subnet router. I connected a Windows machine to my tailnet and using my iPhone's hotspot connected to Tailnet (Windows app was connected, not the iphone one). Everything worked fine.

But on my iPhone it never works without me pinging it from my subnet router.

One interesting thing I noticed, if I ran `tailscale status` before running `tailscale ping iphone172`, it shows `-` in the status column. It changed to `active ....` after the ping.
