Proxy exceptions in Firefox and Internet Explorer
In my office I have to configure a proxy for several Browsers on different Workstations. Also I’ve to add some exceptions for the proxy. I don’t want that local IP’s passes through the proxy. So i have to add it to the exception list in the browser.
In the Internet Explorer you can use a * (star) as wildcard like this 172.17.*. But in Firefox that won’t work. In Firefox you have to add the whole Network-ID with the relevant suffix like this 172.17.0.0/16.
Examples:
You want the whole local IP-Address range in your exception list. Ask your network administrator for the IP-Configuration.
IP: 172.17.72.123
Subnet: 255.255.0.0
When you get this data from your administrator you have to enter the following in your exception list:
IE: 172.17.*
FF: 172.17.0.0/16
If you get diffrent data such as this:
IP: 192.168.0.12
Subnet: 255.255.255.0
Then enter the following in your exception list:
IE: 192.168.0.*
FF: 192.168.0.0/24
I hope that is a usefully hint. If you have any questions please post a comment.
Even better: use a .pac file, which is a centralized configuration file (actually a javascript function) residing on a web server to which you point every web browser within your organization. I’ve been using .pac files for a long time, and let me tell you, the ability to quickly reconfigure 15000 browsers by just changing a single file and redirect traffic to a different proxy is amazing – and has proven invaluable when we had a proxy server failure some time ago.

This sounds good! But in our company the proxy server will be assigned with group policies of the active directory. So I have to change the proxy each time when I boot my computer.
Well hey diddly ho! This worked for me and I’m happy I found you coz there is scant info about this. I don’t have 15000 browsers to configure, only about 20 and this works, Thanks a lot!
