Also, if it matters, Windows firewall will block ping by default. So if you are trying to ping a Windows machine, it will fail unless you explicitly allow it.
Thanks for replying. I’m sorry to splice photo because i only can add 1 media in a reply.
I follow the document and step by step,include
Step 1: Install the Tailscale client
Step 2: Connect to Tailscale as a subnet router
Step 3: Enable subnet routes from the admin console
Step 4: Add ACL rules for the advertised subnet routes
Here is my admin console config. I approve route setting and check ACL rules.(Photo 1& Photo2)
I also try to access a web server on other machine such as (http://192.168.0.107:5000),it failed.
Use tcpdump the output is photo3,No ack reply.
Thank’s for your help.
I give up to solve the problem.
But it was solved by reinstall ubuntu.
I’m using docker to run a mysql server,but it failed to run docker compose.Github issues docker-compose No such file or directory remind me that docker snap has some problem.
So i reinstall my ubuntu server.
Here are some differences:
I close the luks
I give up to preinstall docker when install ubuntu
When these finished,I install docker manually and reinstall tailscale.
This time it works.
