I just wanted to support that last comment, I run a TS480HX thru a Remote Rig setup and get great reports while on the air.
I find it a wee bit fussy when it comes to setting it up at the away end. I plug everything in, turn on my trusty hotspot (so I don't have to deal with hotels/time share passwords), and cross my fingers that I don't trip the Home unit ("Radio"). That happens frequently. And when it does, all I have to do is url the home IP to Reset.
Where the plot thickens is what if the Dynamic IP of Time Warner has changed? What then?
If it does I won't be able to reset the home unit or work the radio.
It raises the question, do the two remote rig units talk to each other and exchange status of the IPs by themselves, ie: do they, when fired up, sync back and forth the IP and then blink the status lights to solid green?
Sorry for maybe butting in but wondered what the last commenters take was on this.

I helped a fellow ham set up a remote rig setup for his cabin. We used 2 routers that supported VPN tunneling. I don't quite remember, but he might have used a static IP address at the remote site (cabin). If not he might have used a dynamic DNS service to find the remote computer, then established the VPN connection between the two sites. This allows you to set static IP addresses on your LAN side(s) and still use dynamic IPs outside. You also get encryption as a bonus.
(off topic) I've also been investigating IPv6, not related to ham radio, but just to keep current on the technology. It seems most ISPs are assigning entire subnets to home routers (known as a /64 subnet... 18,446,744,073,709,551,616 addresses) so that there's no need for NAT, and in theory everyone gets a static IP address for everything on their network. Since it's a routed subnet, it should stick with the device even when network changes are made. I'm sure it will be a very long time until companies like Remoterig get their working with IPv6, but if you can hold out this will all work itself out.
