WatchGuard Blocks some wep traffic

Watchguard X Firewall

Little by little I am learning about this firewall. Have solved some problems but one is getting the better of me.

Parts of some web traffic is getting blocked by the firewall. I do not see errors in the logs to track it down. Good Example is and any item, the Product Overview, Tech Spec's etc are triggered on the page like pop-up. The page works fine but you can not see the pop-up/dropdowns etc. Nothing happens, no errors.

Bypass firewall and all works fine.

Proxied HTTP set : Only setting checked are: Remove unkown headers, Log accounting and Require Content type.  
Safe Content: Neither box is checked.
Overall the Watchguard is working fine but this has be lost.

    have you tried turning off the pop up blocker?

    Disable the pop-up blocker in Internet Explorer 6.x or 7.x

       1. Open Internet Explorer.
       2. Select Tools > Pop-Up Blocker > Turn Off Pop-Up Blocker.

    Disable the pop-up blocker in Firefox 2.x

       1. Open Firefox.
       2. Select Tools > Options.
          The Options window appears.
       3. Click the Content icon.
       4. Make sure the Block pop-up windows option is not selected.
       5. Click OK.

    It is not the PC but the Firewall. Same PC, bypass firewall and no problems. The traffic that it is blocking is not really a pop-up but a drop-down-expand on the page. Since I am clueless about web pages it is hard to say what it is.

    Same issue on IE 6, IE 7, Firefox etc. Just bypass firewall and all works.

    You might be using webblocker and the category might be blocked; also few things like Javascript and activeX might be blocked too.

    Which model of firebox you have also what is the version of WSM software.

    I would like to know if you see any entries in traffic monitor when the page is blocked.

    Please check and update.

    Thank you.

    Firebox X700
    System manager 7.3
    Web Blocker - Not Running
    Nothing in Traffic Monitor when I try to access items on the web page:

    Example Page:

    Page looks fine but any of the 4 boxes from Product Overview to Warranty do nothing. As posted, bypass the Firebox and all works fine.

    We can configure a packet Filtered-HTTP service as below:
    Incoming "Disabled"
    Outgoing "enabled and allowed"; from trusted; to public-ip-of-cdw

    This would ensure that FB is not blocking any traffic which goes out to cdw website; if you wish you can add more website public IP [as you get after doing nslookup] in the to box; please note FB would not filter any traffic which goes/comes from the configured websites.

    Thank you.

    I was looking more for information about what the firewall was blocking to stop part of that specific web page.

    This Question can be killed as I am upgrading the Firewall to a x750e and will redress this issue after the new firewall is placed in production.
