Bridging mode with DHCP server on a client side

alexislg

Hey all,
I know how to usethe bridge mode when the DHCP server is on the same subnet as the VPN server. But now I have a tricky case:

I have:

network A: behind a Firewall
DHCP server that gives 10.254.253.X/24 addresses
OpenVPN client on 10.254.253.166
connected to OpenVPN server
|
|
|
network B: A Virtual Private Server that I use for OpenVPN server
public IP: 37.1.2.3
OpenVPN Server mode tap, TCP443
|
|
|
networ C: behind a Firewall
OpenVPN client connected to the OpenVPN server

Question: How do I configure both clients and server so that devices connected on network C can get an IP address from network A and be on the same subnet 10.254.253.X/24 ? Is it possible ?

Thank you !!
