Ok, so I have a Netopia 3347 model router and Netgear GSM7224 switch...i'm trying to do port forwarding, but when I run a program to see if port is forwarded properly, it says "No". I found in router the place where to do open up the port, i.e. in Netopia they are called Pinkholes, and it still says that its blocked. Do I need to do something in the switch? Please help me out or advice. Thank you in advance.
