Changing the router's port

Ziti Overlay
1

To change the router port I need to change its config.yml and then restart the router.

Unfortunately I need to restart all other routers also.

I miss something?

Interesting. To me if that happens, that would sound like a small bug we have never noticed before. What makes you think you needed to restart the other routers? I wouldn’t expect you to have to do that. How’d you test/make sure this is the case?

I have just modified the config.yml on one host, and then restarted the router.

After that I got errors on all other routers. In the syslog we can clearly see that the all other routers continue to dial the old port number. Thus I have to restart all routers.

We have “connection refused” because the port has been changed.

Hi @Rantanplan

I was able to reproduce this locally. I’ve got a fix which should be in the next release: Other routers don't react to link listener address changes · Issue #3199 · openziti/ziti · GitHub

Thank you for the bug report!
