NAT not working when AirVPN is connected

[WarButter 2]

This is my setup: 
I got 2 machines, a dedicated server machine and a normal laptop.

 

The server is running Windows Server 2012 Datacenter

The server has 6 NICs (Network Interface Connections).

Ethernet 1 has a internet connection to my ISP router which i do not have login access to.

Ethernet 5 (also functions as Mgnt) is connected to my laptop.
 

The setup that i have is that any traffic from/to the laptop on Ethernet 5 goes through Ethernet 1. (a basic NAT setup.)

The server translates the private ip from Ethernet 5 to the public ip on Ethernet 1.

 

This works without problems.

 

 

Heres the problem:
When i connect to an airVPN Server, the laptop loses its internet access..

I want the laptop to be able to access internet. It doesnt matter if thats through AirVPN or directly with the real IP. That doesnt matter at all.

The only thing that matters is an internet connection that the laptop can use.
