I used to use free Windows RDP with Port Forwarding with an older Cisco router.
Worked perfectly but people told me it wasn't "secure".
Bought a new router (RV345 with built in 16 port Gigabyte switch) -- much improved function of office Ethernet, but couldn't figure out how to configure the port forwarding.
RV345 much more complex, and instructions are opaque, to say the least.
RV345 comes with hardware VPN, but couldn't figure out how to configure it for remote access (this is a 2-doctor office -- we don't need heavy duty hardware). Supposedly there is a free VPN connection that works with RDP -- but I couldn't make heads or tails of their "documentation".
Hired our local IP guru -- he worked with Cisco engineer and finally got it to work sort of. Supposedly, there are 2 "free" VPN tunnels available -- I am using one fairly successfully, but we can't seem to make the second one work. There is something called "AnyConnect" which seems to be a licensing scheme, but it is very expensive -- not the sort of thing that a single doctor wants or needs for occasional remoting to the office.
Years ago used LogMeIn -- not bad, but it became ruinously expensive. Same with GoToMyPC and TeamViewer. Right now, I use SplashTop, which is new, and therefor pretty inexpensive.
It works OK, and allows file transfers (at least the "business" version does. Free version does not.
The best solution seems to be Windows RDP through a VPN tunnel -- if you can get it configured. There are probably routers out there that don't require outrageous subscriptions to work -- maybe Asus??
