access client side lan

B-Man

I have a Vpn server running on my home router and have a PI at my parents house that connects to the vpn server as a client.
I can remote desktop into the pi but it is so slow.
Is there a way i can connect from my home pc to the client lan ?
I normally need to access to the routers to change or set something up for them and that can be done but painfully slow through the Pi but now i need to access their solar inverter GUI. and while a cna do that for some reason the Pi web browser shows it as english when loading but then displays it as chinese once fully loaded. so i can't see what i need to edit.

So, from your home PC you can access your parents LAN...
From what you describe it is working, LAN to LAN.

With regards to speed, that can depend on several things.
Your up/download speed
Your parents up/download speed
Pi not that powerful
and some more.

See solar inverters manual on how to change language.

Two things:

Are you sure you have your local network Ok? If the gateway is 10.1.1.253, and the netmask is 255.255.255.252, pcs 10.1.2.2 and 10.1.2.14 are not on the same network as the gateway.

The packet from the Ocean server comes bearing as an IP address the other end of the OpenVPN tunnel, presumably 10.8.0.1. When this reaches 10.1.2.2, this sees it belongs to a different subnet than its own, and will thus try to forward its reply the only way it knows, i.e. via the gateway, not via the OpenVPN client. Hence the return ping never comes back.

The way to circumvent this is to add the following iptables rule on the RPI:

iptables -t nat -A POSTROUTING -d (here your local network) -j MASQUERADE
This way the packet will be sent back to the OpenVPN client. I did not insert your network because it is not clear which one that is: if it is 10.1.2.0/30 please insert that, or modify accordingly.

Hope this information helps you!
