As i have many ports to forward and the port forwarding is limited to 20 ports only i decided to use and the Open ports. But there is one thing that i am not sure how it works.
The port forwarding works for both wan interfaces no matter where the traffic is coming from. The Open Ports is working only for traffic from selected wan interface.
My question: if i open a port through wan1 and this line fails to connect will the trafic from wan1 be redirected to wan2?
