Re: What is my home PC IP address
Whenever I've setup a SFTP server at home assuming the server has a NAT
assigned IP address like 192.168. I've had to put a routing rule in the
router to send Port 22 traffic to that PC.
Otherwise the traffic hits your external IP but nobody is there to listen
to Port 22 traffic which is SFTP.
If you're doing FTP then it would be Port 21

Re: What is my home PC IP address
Indeed, setting up a VPN can play havoc with the routing table, for
example. I was hoping my reply would help to bring such issues to light.

I have used VPN provided by such a site where the required desktop client
completely usurped the desktop's IP stack, preventing all the desktop's
connection to the Internet other than through VPN and the site's firewall
and proxy. This was to prevent any bridging of the site's intranet to the
Internet. It was particularly frustrating to users who couldn't use their
local network printers while connected to VPN.
Of course while they connected to that VPN their public ("home PC") IP
addresses were inaccessible from the Internet.

Re: What is my home PC IP address
In the general case, your PC has an IP address for each interface. I don't know your example setup, but I hope this helps to pose the right questions:- It depends on where your VPN endpoint is. If you VPN to the site where MVS is running, then you should have an IP address on that subnet, as well as the public IP address you started with. Any traffic through that tunnel is encrypted as far as the endpoint. If you VPN to an endpoint at one of the many providers, you'll have a public IP address at the endpoint, and this can be a fixed IP address if your VPN provider does that. Typically, for most of your Internet traffic, once the VPN is up, the public IP address you started with (probably the address of the Internet-facing side of a broadband router) is no longer important. The tunnel has effectively plugged your machine in at the VPN endpoint and how it does it is transparent. I hope this helps, at least a bit.
