I've been unable to resolve this myself and really need some help as my networking knowledge isn't the strongest.
Setup: Flowchart of network
I want to be able to connect to the 10.8.0.2 client that is connected to OpenVPN from the application server at 10.0.0.2.
So far I've tried setting routes via
ip route and iptables SNAT/DNAT with no success.
net.ipv4.ip_forward is enabled on the the application server and the server that is hosting the OpenVPN server instance. I've also ensured that the proper FORWARD rules have been set with iptables that allows forwarded traffic from the /dev/tun0 to and from the /dev/eth0.
How should I go about doing this?
Thank you for your time <3
