Newbie - Port Forwarding

Hi all, sorry in advance for my lack of knowledge on the subject, but I'm hoping someone here will be willing to try to walk me through port forwarding. I've been researching all morning and am stump...

I've got ports forwarded without issue but I'm using the older T3200M and not the wifi hub. Technical support won't help with configuring port forwarding, but it still works. I've tested out port 80 and 8080 had had no issues connecting from outside my LAN (ie cellular or using a VPN). You won't be able to connect directly from your home computer to the WAN IP on the gateway/wireless hub. There are only a tiny number of ports that were blocked now and most are rarely used these days. You can find the specific ports here.

Thanks Nighthawk, I've been trying different configurations, but still no luck and i've been trying to access via cellular, not connected to my local wifi netword. I have a few questions if you wouldn't mind?

 

  1. I've set up a dynamic dns, if i understand correctly, i should just be able to use this with my desired port number in place of my public IP and it should keep things working in the event Telus changes my public IP? So for example: mynewddyns.org:18080 would send the request to public port 18080?
  2. If i set my port forwarding options to public port 18080 and private port 8080 (or maybe 8081, some posts say it's 8081, but i'm trying both), this should work with the above?
  3. would i need to check the tick box in my firewall settings to allow traffic in for port 18080 or is this the whole point of port forwarding? ie. it allows access through the firewall even if my settings are such that incoming traffic is blocked?
  4. My default firewall settings are all traffic out only, but when i search for ports using CanYouSeeMe, it says they're available, even the ones that are specifically noted in my list of ports that don't allow incoming traffic... is this normal? Hopefully the images i included in the original post are visible and you can see what i'm referring to.

Thanks again!
