Got it!
I was erroneously thinking that the port # on the toolbox address entry was the 49300 port... but now I know that it was supposed to be the HTTPS port instead.
The "Port(if not default)" does not give any hint about this.
Anyway, I was able to get this to work.?

Now, for the greater good I want to suggest Anydesk for those of you that need a quick way to get direct access to a remote system when all you have is somebody with a laptop on the other side.?
And by that I mean you can directly access the processor or VC4 in your laptop as if you were sitting inside of the far-end network. (Because I hate when you are constrained to using toolbox on a remote machine through Teamviewer, It makes me claustrophobic!)

The feature is called TCP Tunneling.
Here are the instructions:
Once you have anydesk connected to the remote laptop, look for Actions -> Setup TCP Tunneling.
Then in there you will punch the usual ports. Note that "remote host" is the IP of the crestron processor (or VC-4) on the other side of the network. The example shown here is what is needed to access an appliance box (non-VC4).?
LocalPort? ? RemoteHost? ?????RemotePort
41794? ? ? ? 192.168.10.55? ? ? 41794
41796? ? ? ??192.168.10.55? ??? 41796??
22? ??? ????? ??192.168.10.55? ??? 22
?
Once you have the TCP Tunneling rules in place, on your toolbox you have to enter the loopback IP in the address field: 127.0.0.1
So when toolbox connects it will go through this path:
Toolbox -> loopsback into... -> Anydesk forwards to... -> the far-end Laptop, which in turn forwards to... -> the far-end crestron processor.
The big advantage of all this is that it allows you direct access to a far-end processor without any need for VPN nor having to ask anybody to open ports on firewall etc.?
All you need is somebody with a laptop running Anydesk on the far end. Thats it.
For VC-4 the steps are the same as above but you also need to add rules for 49300 and also forward the HTTPS port, such as this:
LocalPort? ? RemoteHost? ?????RemotePort
41794? ? ? ? 192.168.10.55? ? ? 41794
41796? ? ? ??192.168.10.55? ??? 41796??
22? ??? ????? ??192.168.10.55? ??? 22
49300? ? ? ? 192.168.10.55?? ? ?49300
443? ? ? ? ? ??192.168.10.55?? ? ?443
One final note is that AnyDesk by default has TCPTunneling grayed out. The person on the other laptop must explicitly tick a box allowing you to use this feature.
If you poke around the settings, you can configure a laptop to give you convenient unattended access.
I highly recommend AnyDesk, and no, I'm not being sponsored by them :)
