Thanks for the insight, I do already use the Firewall to filter out those ports, I only use the service ports filter as a secondary. However, with regards to the putting my DNS name into the input field should be allowed, i just don't see why not? I have a DDNS on my router (my routers IP Address might be changing soon to IDK what) and want the remote router to be able to use the new IP address which is why I wanted to put the DDNS name of my router on that field. Again, this is only used as a secondary. Its not that big of a deal, however, I dont see why this field should discriminate against DNS names being entered into this field.
