Definitely outside the scope of this community but hopefully someone here can give me a hint if this is possible to achieve.
I have two remote sites with X12 and X50 as routers. On each site there are Unifi APs for the wifi that I have setup independently by physically moving the Unifi Cloud Key between the sites.
My key question: Is it possible to configure the Teltonikas so that the Unifi Cloud Key can reach the APs on both sites without having to move it physically?
I am a rookie when it comes to this area so just a hint from one of you if I should close this idea immediately or spend a few days trying to set it up would be highly appreciated!
If establishing a L3 connection is indeed enough to access and manage the devices, I recommend considering the use of a VPN like OpenVPN. You can find configuration examples for OpenVPN here. Additionally, there’s an option to set up OpenVPN in TAP mode, which effectively merges your network (same subnet) and provides L2 connectivity (example here).
However, please note that with OpenVPN, one of your devices (acting as the server) must have a public IP address. In cases where a public IP address isn’t accessible, an alternative is to consider ZeroTier VPN. ZeroTier operates without the need for a public IP address; instead, it relies on ZeroTier servers. The free tier of ZeroTier should suffice for your requirements. You can find a configuration example here.
