SmartSDR + DynDNS in place of SmartLINK for remote operation?

Member ✭✭
edited January 2022 in Remote Operation (SmartLink)

My remote Flex-6400 is in Florida while I am in San Diego. I am presently using SmartLINK and it is working fine.

I also use DynDNS to remotely operate another radio at the same site. It is connected via a pair of RemoteRig interfaces, and it is also working fine. I am also remotely managing a SPE Expert 1.3K FA amp and a rotator using RemoteRig's 1216 devices.

As the remote is on a dedicated cable modem, I am subject to Dynamic IP changes at the whim of the cable provider (Spectrum). So, I have been using DynDNS and haven't had any issues over at least three IP address changes done by Spectrum :-)

My question: If I setup my remote router to port forward ports TCP 4994 and UDP 4993 to the Flex, can I then just run SmartSDR and not have to worry about SmartLINK?

Local: Connect to "DynDNS address:port" --> Remote router is configured to port forward TCP 4994 and UDP 4993 to the Flex' LAN (Reserved IP address) matching ports.

Would this work?

What am I missing?

Would I be able to use SmartSDR from here to the radio as the link would be as if it was on the local LAN. If so, I would no longer need SmartLINK and rely on Flex' server for authentication

    The short answer is no, at least on the Windows version of SmartSDR. I believe you can on the Mac version, but I have never tested it.

    At this time, we will likely not make that change in the Windows version for a variety of business reasons.

    If you need a Plan B in case there is a SmartLink issue, you may find that using SoftEther as a VPN will work very well.

    A Smartlink connection uses less bandwidth than a LAN connection, even if the LAN is on a VPN.

    SmartEther has been well discussed as one solution in the FlexRadio Community. There are many others as well, and I am sure many will comment.

    I hope that this helps.

    Yep ... it was just a thought after watching one of your videos.

    It kind of made sense to me as I am using this type of setup to remotely manage the TS-480SAT w/RemoteRig interfaces. I was (wrongly) assuming that I would be able to do the same.

    After all, the "Ethernet" connection is just a "long cable" connecting my computer to the radio. So, if I port-forwarded and made sure the router and firewall were configured properly, that it would work.

    SmartLINK is working ... but as a curious techno-ham, I am always looking for "other ways" to do things. I will check SmartEther and other VPN solutions. I do have a NUC at the remote site as it lets me manage the Flex on the LAN side. I just prefer running the software over here. I will check to see if the NUC I have at the site is capable of reliably running SmartSDR as that would be my backup :-)

    Thanks again.
