Hello:

I have a web application that requires to activate the ports 80,554, 1111, 7070, 11165, 1755 to display video. However, when I plug into comercial LANs such as Verizon DSL or DSL at hotels, I cannot see the video. Pretty much I can only see the video at work.

How can activate the related ports?

Hi rlopez98,

When you say "activate the ports", do you mean open these ports for inbound traffic?
The only way you'll be able to do this is for whoever manages the connection (more specifically, the firewall/router) to configure it to port-forward to your device.

That's not a particularly practical option, and difficult to do in most circumstances.

The only other option that I can think of is to find some sort of tunnel solution (all the data gets relayed through an external machine).

Thanks,

Yes, basically what I was told to do is to Open these ports for inbound traffic.

Can I control my own router to open those ports? I need to be able to have those ports open while I'm in the road as well.

Any other options?

Cheers

rlopez98:
What you can do really does depend on what the service-provider is offering you.
If they provide you with a DSL line and no restrictions, you can configure your own router to do whatever you want.

However, I imagine that hotels and other locations will simply provide you with an ethernet port (or wireless ethernet) that connects through their router/firewall.  In this case they can block whatever they want.

This issue is also a problem with Voice Over IP (VoIP) - which sounds similar to what you're doing.
A system has been developed to help solve problems with NAT routers and blocked ports - this is called STUN (Simple Traversal of UDP through NAT).
It's an IETF standard, available at http://www.ietf.org/rfc/rfc3489.txt

In this case, your STUN client (your PC/VideoPhone) contacts a STUN server.  The STUN protocol will then work out the best way of communicating between your client and the VoIP server.

I don't know how much use that is for you, but might give you a couple of ideas.

Your best bet is to speak to whoever provides the application and see if they have any suggestions.
