Closed Port
I work remotely and I am having issues using HighFive for conference calls. When I try to use it, it tells me that I need to open Port 5005. Is this port blocked by Cox? Is there a way I can check my modem to see if it is blocked there?
Thanks.

Cox doesn't block that port, as per here, but your router or computer may. Does the HighFive client use UPnP? If so, make sure that is enabled on your router. What model router or gateway do you have?

Hi LadyValeria, That port is not one that is on our blocked list, click here for more information on the ports that are blocked - http://www.cox.com/residential/support/internet/article.cox?articleId=cacf82f0-6407-11df-ccef-000000000000. Hope this helps!

According to Highfive's support site, 5005 is required as an outbound udp and tcp port. It also required an mtu setting of at least 1360 bytes. Are you running software on a computer or a Highfive hardware device? A firewall running on you PC could block the port. Again, what router or gateway do you have?

TCP 5005 is also same as RTSP. Most routers have NAT passthroughs which you can enable for RTSP. 5004 is used for upstream, or what you speak, and 5005 is downstream, what you hear.

I have a Belkin N300 (Model Number: F9K1002V5). I have been on their forums and they show me how to port forward, but it still shows as close even after I follow their directions. I have enabled a DMZ for the private IP of my work computer to put it outside the router's firewall. When I run a check to see if the port is open, it says the reason it cannot find my computer is because it timed out.

Do you have tech support at the company you work for. Maybe they can help out more than these forums. Anyway, since you are still having problems with the computer in the DMZ, leads me to a firewall or something running on the computer blocking the connection. A final test, remove the router. Connect the computer directly to the modem. Turn the modem off (or unplug) and also the computer, Connect the computer then power on the modem. When the lights are stable on the modem, start your computer. If it still doesn't work it is definitely something running on the computer causing the problem.

I looked through the Belkin manual, but it has almost nothing on adjusting the firewall or WAN passthrough settings.
I would suggest connecting the PC with the application direct to the modem and see if that works. That would rule out anything on Cox side, or anything with your PC firewall. What model modem do you have?
