It sill works but I ended up not using bridge and went with this.

@black3dynamite ??? I don’t see anything about bridging in here...

I found a updated and working guide here:

That's because your using NAT and IP Forwarding instead.

When using the Bridging feature, you should be away that devices on Side A of the bridge can get DHCP addresses from Side B and vice versa if you don't block DHCP from going across the ZT network....

I have actually switched to letting ZeroTier do more of a site-to-site VPN setup now. Each site has a Linux VM that routes traffic through ZT.

Clients that connect up to that ZT network also have access to the sites as well since ZT passes the routes off to the clients.

@dafyre - I had used your instructions a while back and everything worked perfectly. A couple weeks ago, I was setting this up for someone else and couldn't get it to work. After messing around with it for a while I noticed that Zerotier has the Rules section in the control panel. I took the rules from my old working setup and pasted them into the rules on the newer network. Everything worked perfectly after that. Not 100% sure what was different from the old rules vs the new ones but definitely a change in their default Rules makes it not work correctly.

Good to know it still works!

@dafyre can you explain your setup in more detail?

@Curtis -- Do you mean my current set up?

I'll do a new post for that.
