My Net N900C Print Share not working with Norton Security Suite by Comcast

WD Print Share is not recognizing my printer when attached to N900C unless I disable the firewall on Norton Security Suite that came with Comcast internet. Does anyone know how I can work around this or add a firewall rule to fix this? I just hate to disable then re-enable it just to use the print share app. Any help understanding this would be greatly appreciated. 

You can try putting the printer on DMZ.

Check with the firewall manufacturer for information about other settings that will help with the connectivity issues.
