If you want to open a port on your firewall you can do so by logging in to the web GUI of your firewall but I would not do that unless you know exactly what you are doing as opening a port on a firewall potentially opens a huge security hole in your network.  Instructions on how to do that for this firewall can be found here.  Go to page 26 of the PDF.  You will need to plug a computer directly into the firewall on a specific port and you will need the user name and password to the firewall.

Now some questions:
Is your website hosted from within your LAN?  i.e. Are your computer and the server hosting your website both on the same side of the firewall?
What makes you think that your issue is related to your firewall at all?  Based on your symptoms, it sounds more like your browser and/or local computer security settings.

A website by itself only uses port 80 for a regular connection or port 443 for a secure connection.  There are a lot of other ports used in the operation of a server but that's all for just the web site.

You could use a portscanner to see what ports are open http://www.radmin.com/products/previousversions/portscanner.php

Can you access any website at all?  Is your website on your LAN?  If it is public, can you give us the address so we can check it?

MY website is hosted in US , what makes me think the issue is related to Firewall is because i can access the link outside of my company's premises . I have a strong feeling that the issues lies on my juniper firewall or else on my ISP Proxy servers . I know how to access the interface of my firewall all i am asking now is how to open a specific port in  my jubiper firewall which i have already checked using port scanner ( 0-65535 port is closed ) i need to open this port  8080 lies in this range

thanks

If the website is hosted in the US, which I presume is an outside on the Internet from your firewall's prespective. Why would you want to open port 8080 on your firewall? Does an application or feature on your LAN or Firewall require you to open that port to access this site?

With the description given so far, I also don't think it is your firewall. Try these steps to see if you can get closer to resolving your problem.

1. If this is possible try resolving against different DNS servers than your ISP ones. Like Google name-servers or OpenDNS name-servers.

2. When you are in command-prompt. What do you get when you type  "telnet [your website] 80", then type "GET" then hit Return. if you see the HTTP header with some 400 or 500 returned status code it means the website is listening to port 80.

3. These hyperlinks that you cannot access within your website when you are within your LAN. Are they linking to files or documents elsewhere and is the URL change at all to HTTPS or does it stay the same?

4. On command-line prompt again, can you try pinging the links that seem to not load and see if they resolve at all?

Please tell us the nature of the problematic link.  What kind of data does it link to?  Where is the data stored? Same site as the webpage or is it a link off site?  What is the nature of the error?  When you click on the link does nothing at all happen or do you get an error message or garbled data?  If the latter, what does the error say?  If you are still convinced that it is your firewall, that link i posted shows you how to open ports to specific protocols without opening security holes.

as i am writing this email i am in branch office and i dont have problem in opening the link (a link inside the website )  , but back in my office  where my firewall is implemented the error i am getting when i try to access the specific link is Network error (tcp_error)
A communication  error occured ,the webserver may be down too busy or experiencing other problem from responding to your requests ......

Unless i use a proxy setting in my web browser (IE8) i am not able to access the specific link from my LAN .

Advise  ?
