I have two iPhones that connect to my DIR-655.  On those iPhones I am running software that requires UDP port 14666 be open in order that the software packages on each phone be able to communicate to one another.

I get the concept of allowing communications from the outside, on a particular port, to be forwarded to a given IP address.  And I think this would work wonderfully if I were communicating between an iPhone on my network with an iPhone on another network.    But I have two iPhones behind the firewall, and for some reason, they are unable to communicate to one another.

The closest I have come is when I setup port forwarding and make the 14666 route traffic to the IP address of one of the iPhones.   When I do that, I keep seeing the other phone briefly connecting, and then dropping the connection.   But short of that, I never see connectivity between the two devices.

I am confused as to why the router would have any dealings with traffic between two computers on my internal network, on any port - wouldn't that be restricted/controlled by the devices themselves?

In any event, the router evidently does have an impact, and I am at a loss to understand how I can have port 14666 open between these two Wi-Fi devices.   Any advice would be greatly appreciated.

Thanks,
-Neil

Under the Advanced tab of your router's configuration page, pick "Advanced Wireless" on the left.

Make sure "WLAN Partition" is NOT checked.  This feature prevents wireless devices from communicating with each other.

There is no wireless firewall which would prevent your specific ports from working that I am aware of.  I've had two iPod Touches here playing games and one connects to the other fine.
