Routing question, I really need help :-(
Posted: Sat Mar 03, 2018 9:01 pm
Background:
"Home subnet" 192.168.1.0/24 (OpenVPN server runs here)
"Remote subnet" 192.168.8.0/24 (OpenWRT router)
"VPN subnet" 10.8.0.0/24 (assigned to remote subnet users from OpenVPN server)
"Tethered" 192.168.42.0/24 (IP range assigned from tethered mobile)*
* I assume the "Remote subnet" routes through "Tethered" ->Interent
===============================================================================
NB. Remote subnet accesses the Internet via a mobile 4G connection (tethered)
===============================================================================
When the VPN connection is established from "Remote subnet" <-> "Home subnet", then "Home subnet" CAN ping 10.8.0.0/24 VPN clients and access the web interface on 10.8.0.2 (the VPN assigned address of 192.168.8.1 (OpenWRT gateway)) but cannot access the remote routers local LAN IP address of 192.168.8.1).
"Remote subnet" cannot ping clients on "Home subnet"
"Home subnet" cannot ping clients on "Remote subnet"
This is getting complicated and I am getting lost!
I would like to be able to access ALL clients on 192.168.8.0/24(Remote subnet") from 192.168.1.0/24("Home subnet") when a VPN connection from 192.168.8.0/24("Remote subnet") is established.
"This would allow me to retire the reverse SSH tunnels I have in place"
Optionally it would be great if I could get two way communication between the subnets.
Any advice, greatfully received.
