NAT over OpenVPN tunnel

optize

I have an interesting problem. I have two networks.

Network 1:

10.0.15.0/24

Network 2:

192.168.0.0/24

They can ping each other, all is well.

However, the problem comes when I'm on the 10.0.15.0/24 network and I want to reach one of my SuperMicro IPMI boxes, which are on the 192.168.0.0/24 network and you can't modify their routing table to point 10.0.15.0/24 back to the VPN gateway, and you don't have control over the network gear in the facility.

Is there a way to do some kind of NAT on the 192.168.0.0/24 VPN side so all connections from 10.0.15.0/24 block, which go to the 192.168.0.0/24 use the gateway IP on the 192.168.0.0/24 block and therefore can reach everything internally without a route (because it'll have a 192.168.0.0/24 IP....?

I'm sorry if that makes no sense, I can draw it out if easier to understand.

I have no control over the server side LAN on the 192.168.x.x block. It's at a hosting provider, which obviously won't let me control how routes flow within their network.

The goal here is to be able to access my IPMI devices from my 10.0.x.x IP block, but since established traffic doesn't return, that doesn't work unless I can find a way to NAT it.

Here's a quick network diagram:

Me (10.0.15.251) can ping 192.168.0.38 because there's a route for 10.0.15.0 back through the tunnel. However, since we can't add static routes on Supermicro devices, that won't work.

Talk to your provider.

Alternatively, run your own OpenVPN server and have your device connect to you.

Hi,

Thanks for the reply but I don't think you understand. I am running my own OpenVPN server and I can't "have a IPMI connect to me"
