Using ZeroTier one

Apparently.

However, the configuration is not trivial or plug and play.

I like the concept and it works well for my remote desktops. That was pretty simple to set up.

I wrote this 'wedge' the other day and I was given permission to share it. I use it from time to time for testing over a VPN when I need to eliminate SmartLink.

This will allow you to see your radio over most VPNs. It is a great little project if you want to learn about SubNets and IP Addresses. Feel free to give it a try if you are adventurous, or, maybe you can build the better product. Maybe Mark will add it to FRStack.

Most of the details are on the GIT page, but essentially, this Python3 script runs on my PC (or a PI) on the local user network (subnet). What it does is spoof the radio on the local net but when your SSDR client sees it, it has the IP address of the radio and it will then connect to the radio on the other network.

It only works with the radio but not 4O3A products, but those crafty enough could figure that it out pretty easy and add their broadcast messages.

When you get to the config.ini file, yes, those are my exact settings and you have to change them all to match your radio. My radio is a 6600.

You will also need to change the IP settings to match your network.

There are a number of other settings in the UDP broadcast that likely should be changed if you are using a single SCU radio, but I am not 100% sure how critical it is. That info is normally just used for the Radio Chooser to do its thing and present some user data.

And, I'll fess up. I used ChatGPT to code 99% of this. I just fed it a sample udp radio broadcast packet and it mostly worked the first time.

*** Do not open a support case if it doesn't work. :) Otherwise, I will be at the rath of Mr. Tim. :) As well, do not open a support case for a remote issue over a VPN using this or anything similar. They will ask you to test on SmartLink and if it works the support team needs to move on. Sorry, but it is a bandwidth issue.

It comes with zero support from me simply due to other time constraints. But, we have enough elmers here that can quickly understand how it works. Or, maybe build something that run on a PC GUI rather than in a comand prompt. I would be happy if someone made it their own.

Have fun and I hope you learn something.

It should work as long as your VPN tunnel passes directed UDP traffic from 1 subnet to the other, which is different than broadcast traffic.

This may require that a rule is opened on the Server/Router to allow for this to happen. Depending on what your FireWall rules are, you may need to adjust them.

And, if it doesn't work, WireShark is your friend. It is a great tool and for those that don't know how to use it, there are lots of videos.

You only need a few tools. These are the ones I use all the time:

• only show based on an ip address
• only show based on Port data (4992 in this case)
• Follow TCP Stream
• Follow UDP Stream

If you are having issues, there are likely a dozen reasons why your VPN tunnel is blocking communications.

Good luck and have fun with it. Expect a hiccup or 2 if you are not savvy with basic network communications. But, you will learn something.
