I was able to configure a basic setup with openvpn server, clients are connecting and going to the internet.
However, the issue I am facing is that the clients use the same default gateway like the one configured on the VPN server OS, which is not what I really need.
My requirement is that the traffic uses the following path:
client <---vpn tunnel--> vpn server outside interface <-> vpn server inside interface <-> gateway (different from VPN server OS gateway) <-> internet
What is the recommended approach for this kind of setup?
I am thinking of 2 solutions, but don't have enough experience to know which one is more suitable:
1) use bridge mode (TAP) for the clients (not preferred in my case)
2) use routed mode (TUN) create a separate routing instance for VPN user originated traffic to send traffic through the VPN client GW
Note: I do not want to use masquerading anywhere
