Brmstech,

Under Firewall for the DIR 655 change "UDP NAT ENDPOINT FILTERING" to "NAT ENDPOINT INDEPENDENT"

Here is an emulator: http://support.dlink.com/emulators/d.../Firewall.html so you can see what I am referencing.

Also at the bottom you will see a checkmark box for 'SIP' (ALG). Uncheck this box.

Once that has been updated & saved -- power down all network devices and then power back up all network devices.

Let me know how this works out for you, thanks!
