Watchguard Firewall - Request Denied ??

I hope someone uses Watchguard Firewall. I cant seem to find any active groups for this particular Firewall product.

Here is my problem.

I'm not expert on the Watchguard / Firebox 700 and am having the following problem.

We log onto our paid subcription to yahoo mail. Then we click on the contacts tab which opens another window that gives us the addresses in our address book. Unfortunetely when we do this from behind the watchguard firewall we get the following error in the browser.

WatchGuard firewall: Request denied for http://216.109.xxx.xx:80/mail_ca/pimnav/ab/*

Unsafe URL `/mail_ca/pimnav/ab/*' denied

The Traffic Monitor Reports This .....

03/24/08 11:22 http-proxy[30812]: [10.1.0.117:4179 216.109.xxx.xxx: 80/mail_ca/pimnav/ab/* Request denied: Unsafe URL `/mail_ca/pimnav/ab/*' denied

The actual site in the browswer seems to be ...

*

This works from computer that are not connected through the firebox. I'm no expert on the firewall, it has so many features its hard to know what to do.

Anyway I have added the IP address above 216.109.etc to the http Properties/WB:Exceptions and also added it to the Proxied-Http WB:Exceptions but this does not seem to allow us to view our contacts. It gives the same message as originally listed above.

The error message seems to be saying that the url `/mail_ca/pimnav/ab/

*' is unsafe. I'm not sure where or how to allow this??

Thank you.
