    Your "WAN" and LAN networks are the same ( Every other packet sent from the server computer goes to the wrong network since from the OS point of view both NICs are equal and it tries to balance the connections.

    When the server wants to send a packet to the internet, it looks up the gateway ( Then it looks at its network interfaces and sees that they are both connected to the network. It picks randomly one of the interfaces and sends the packet away, not knowing that the gateway exists behind only one of the NICs. The same happens when you are trying to communicate with your local network.

    Change one of the networks to some other address.
