add a route to a specific IP on linux to get to a remote emulated system


Note on how to add a route on a system remote to an host for an emulated system.

Use case.  A system with TCP/IP configured is running on a host with a local IP for the emulated system, and a gateway IP on the host.  The latter  is on a tun/tap NIC on the host system.

one can access the emulated system from the network on the host system.  But the gateway tun/tap device isn't shared on the external network.

example
[hercules guest]
ip xxx.201  NIC internal to OS
[CTCA bridge]
ip xxx.151  NIC tun/tap on host running hercules
[Host system]
ip xxx.136 NIC is enp0 ethernet NIC for host.
[subnet]
xxx/24

[remote system]
ip xxx.172

traffic for the xxx.151 ip isn't bridged out of the [Host system]

ip route add xxx.151 via xxx.136 dev enp0s25 executed on the [remote system]
allows programs on remote system access the [hercules guest]

currently redirects to:

How to use
    • Download the latest Raspbian image from [ https://www.raspberrypi.org/downloads/ ]
    • Flash your SD card as usual using Etcher or Win32DiskImager
    • Open up the "boot" partition and edit "config.txt", adding "dtoverlay=dwc2" to the bottom
    • Open up "cmdline.txt" and add "modules-load=dwc2,g_ether" after "rootwait"
    • Create a new file named "ssh" in the boot folder
    • Insert this TF card to Raspberry Pi Zero/Zero W
    • Pop your newly set up SD card into your Pi Zero
    • plug it into a USB port and you should be able to SSH in to "raspberrypi.local",
    • you will need Bonjour, iTunes or Quicktime installed in Windows or Avahi Daemon in Linux for this to work.
