How to Stealth port 8000?

[Firewing1]

Hi all,
My site runs on DynDNS.org, and I have Videotron, so they block port 80. I set it up to port-forward etc... But, now, my port 8080 and 8000 are left completely open. My port 80 is stealthed, although I did the exact same thing for it as I did for port 8080 and 8000 ( In Firewall settings, and router...) Is there any way to "filter" or "Stealth" port 8080 and 8000? (As in, it lets HTTP connections, but nothing else...)
Thanks,
