[hpsdr] Hermes board Ethernet Port number

[Tom McDermott]

Hi Ingolf,   it would be helpful to understand what you are trying to
accomplish.

OpenHPSDR V1 and V2 both use broadcasts to find target devices on the local
subnet via port 1024.
Such broadcasts are not routed (as George previously indicated), the
various HPSDR application programs
will not find an openhpsdr device on a different subnet.

In order to have a remote device be found, a VPN is generally used to
extend the local subnet tunneled
through the internet to a remote location which then would have that same
subnet address range.  Various
VPN protocols have emerged in the last few years to make that a bit easier
than it used to be.  With a
VPN your home internet router passes the VPN protocol, it does not see the
raw broadcast frames or
port numbers as those are inside the VPN tunnel.  Merely opening a port
(destination NAT) on your home router
would not allow you to remote to the OpenHPSDR device through the public
internet.
