As far as I know Zero Tier needs extra settings to rout all traffic through VPN server in my home. There are some articles how to set it, but I didn’t find even one how to set it using Zero Tier in docker. Especially on Synology server.
The point is to route all traffic through the VPN server. Connecting with computers in the same Zero Tier network is not the issue.
*route all traffics - means if I use phone / notebook the connection to https://example.com go like notebook <-> server in home <-> https://example.com and this is the point and I didn’t find article how to achieve it using docker on Synology.
PS there is no other way to run Zero Tier on Synology as a plugin / application. Only one way is to run it as a docker.
