Tunneling a VPN for Maestro

The present release series of SmartSDR in all favors (for Windows, for Meastro, for Server) have local area network connections implemented, but that everything on the same LAN is limiting.

I’ve long wanted to be able to run my home station from my office as often DX opportunities happen only when I need to be on site working.

FlexRadio System has announced that the LAN barrier will be broken with version 2.0, and that is a ways out.

Chris K6OZY has kindly prepared a couple YouTube Videos and notes on how to use SoftEther VPN with two Raspberry Pi units to create a VPN server and a VPN bridge unit.

There are other ways to do a suitable VPN but this has advantages worth considering.  Read the FlexRadio Systems Threads on the topic to look through those.

Amazon sourcing for the hardware:

With help from son Winston KC9FVR to fit the error I made, the server and the bridge were set up.  Took us two evenings mainly because I wanted to do a fair bit myself rather than letting “Mr Geek” KC9FVR do everything.

Results are fabulously fun!!

What more is there to say?  Ran QSOs until KC9FVR reminded me he wanted to head off to sign up for his next classes on some on-line University system,

Downing everything has not been a problem, but we will clone the SD Cards for both the Server and the Bridge next.

Catch you on the air!

Here is the overall setup. I don’t usually get to set computers up on the kitchen table.

fldigi running Feld Hellschreiber in transmit mode.

Haven’t put it on the air yet – still trying to resolve some of the artifacts from processor overloading.

This is the Raspberry Pi itself, cased in a Pi-Shell.

Lots of cables.

I picked a decent powered hub, and power the Raspberry Pi itself from the hub.

I tried a less costly hub and had keyboard issues wwwwwhhhhhhheeeeeerrrrrreeee it couldn’t read the keyboard and other random reboots.

I really needed the first book. I haven’t dug into the second one yet.

Here is the Raspbian Wheezy default desktop.
