Summary #

WebEx is a web-based conferencing software solution, which allows participants to watch the same screen and collaborate during a presentation.  The WebEx software appears to ignore the proxy settings in the browser in certain circumstances, so firewall rules are needed to permit traffic to the WebEx servers.

To make WebEx work through SecureSchool, you need to create several firewall rules.  Go to “Firewall” -> “Protocol Rules” -> “Add A Rule”.  Add a rule using these settings:

• Rule Name: WebEx
• Log Packets: None
• Type: Allow
• Protocol: TCP
• Direction: From Inside
• Source Address: “0.0.0.0/0”
• Source Port: Leave blank
• Destination Address: “66.163.32.0/19”
• Destination Port: Leave blank
• Notes: Fill in any notes you’d like

Repeat the process above with the destination address “209.197.192.0/19” , “64.68.96.0/19” , “66.163.46.0/23” , “66.114.160.0/20” , “66.163.32.0/20” , “208.8.81.0/24” ,  “210.4.192.0/20” , “62.109.192.0/18” , “173.243.0.0/20” , “114.29.192.0/19”

Once you add the two rules, go to “Commit Changes” then restart.  You should now be able to use WebEx.
