Recently installed Tailscale on home PC running Win 10 Pro behind router/NAT and on Win10 pro laptop. Installations was all OOB with defaults, no Magic DNS or other options.
Tailscale was working OK when on the same W-Fi network and via USB tethering on my phone so I know it was working when connecting from an external network. I could ping and connect an RDP session on using the Tailscale IP as shown in the admin console for the Home system.
Today the laptop isn’t connecting via different Wi_Fi or by USB tethering. Tailscale admin screen shows it as connected and running v 1.8.7, but ping to 100.101.102.103 fails (no response).
sleek==laptop
smooth==HomePC
I can VPN to ‘Smooth’ and it pings 100.101.102.103 OK. So that tells me that end should be OK. Nothing so far on the laptop end has made a difference, reboot, restart TS client etc.
I can’t find anything on what ports TS needs open, some I’m wondering if windows Defender/firewall is blocking outgoing traffic?
Here is what I get with ping attempts on ‘sleek’:
C:\WINDOWS\system32>ping 100.101.102.103
