[Openvpn-users] Using a VPN client connection to reach the remote dir from the VPN server's LAN?

[Bo B. <bo....@gm...>]

This is kind of a super-strange usage question for OpenVPN but I would like to
know if it is possible and if so how do I configure it:
-------------------------------------------------------

I have a couple of devices (mostly Raspberry Pi units) deployed on a few
locations outside my home LAN and these connect back home using OpenVPN clients
on them.

While they are connected I can SSH into their command line interface for
maintenance and checking using their tunnel IP addresses. That is very
convenient.

But...
Now I wonder if these clients can be set up such that when they are connected to
my main network through their OpenVPN clients they also act as a gateway back
into the LAN they are sitting on?

That would open up a simpler way to manage the *other* devices on the same
remote LAN than configuring each of them to connect back home using an
individual OpenVPN connection that is already connected.

They really do not need to connect back home for the functionality they are
handling but only if I would like to reach them for config changes etc.

As I *can* connect by SSH through the tunnel back to the device that is
connected to my home LAN then I could also reach the remote LAN via that device.

So for command line access to the other items that would be fine.
However, some of them do not have a command line entry point (no SSH) but only a
GUI http config interface and that cannot be used via SSH to the vpn client.

So can it instead be configured such that I can use my config GUI app at home
chanelled via the client VPN connection back onto the remote LAN to reach these
GUI style devices?

If so how?
