OpenVPN Behind Firewall One Nic it is possible?

[mosquitohippy]

Hi

I'm trying to setup a site-to-site VPN with pfsense and openVPN, so i'm setting a pfsense in a ESXi's VM with one interface with one private ip address, then i'm planning to implement port fordwarding on my firewall for the standard openVPN port pointing to my server in the ESXi.

The other end of the tunnel would be another pfsense openVPN in client mode.

The Client PC's should use a static route to point traffic to the intended hosts through the openVPN Client in the other side of the tunnel.

Is this configuration possible?, i'm concerned about the one interface setup, but i don't see the need of more interfces, am i wrong?

Thanks in advance
