CM600 + Router Port Forwarding

I'm trying to configure my router to port forward TCP 3389 so I can use Remote Desktop.  I've tried two Netgear routers and both have the router blocking the forwarding effort.  i see the router log ...

    The mac address is my Sony Bravia TV.  I've turned that wireless off and now it is forwarding - but mcafee firewall is blocking.  i will fix that - thanks for your help.

The WLAN access rejected MAC error message is unrelated to port forwarding.  It is related to MAC address access control and is logged whenever a home device attempts to access the home network but has not been whitelisted.  

 

Something else is going on.  Either you didn't set up port forwarding correctly or port forwarding is broken.

    Thanks for the message.  I didn't set up MAC access control so any suggestion on how I can turn it off?

      What's the model of your router?

        I'll give you the full setup.  I have theCM600-100NAS connected to Xfinity.  The ethernet output of the CM600 goes to a NETGEAR N750 Dual Band Wi-Fi Gigabit Router that is configured to be the DHCP server for the LAN  (WNDR4300)  .  I also have a NETGEAR N600 Dual Band Wi-Fi Range Extender - Desktop Version with 4-Ports but it's not being used for the PC i'm running the test on.

         

        I'm set up for port forwarding from the WNDR4300 to an HP Laptop, added the WiFi password but otherwise left all router settings at default and loaded the latest firmware.

         

        I ordered the WNDR4300 because when i got the CM600 i tried to use it with an older N150 router (WPN824N) and i could see the WLAN error in the log each time i tried to test if the port was open on the laptop using canuseeme.org.   The webpage sees the WAN IP address but never tries to forward and records the MAC WLAN error which my net research shows indicates a possible hacking attempt.  I had port forwarded before I ordered the CM600 (had modem/router combo's) but now that i have a pure modem i can't get the router to work.
