<p>How do I configure a Personal Firewall / Router for my Blackboard Collaborate web conferencing or Elluminate Live! session?</p><p><div class="KBAnswer"> <h3>Configuring your personal firewall</h3> <p>When using Blackboard Collaborate web conferencing or Elluminate <i>Live!</i>, you may need to configure or confirm settings in your Personal Firewall. We have included information for the several popular firewall applications. If the personal firewall application you are using is not in the list, see the General Tips below.</p> <ul type="disc"> <li><a href="http://support.blackboardcollaborate.com/ics/support/default.asp?deptID=8336&task=knowledge&questionID=57" target="_parent"><b>Norton Personal Firewall (Norton Internet Security)</b></a></li> <li><a href="http://support.blackboardcollaborate.com/ics/support/default.asp?deptID=8336&task=knowledge&questionID=56" target="_parent"><b>McAfee Firewall</b></a></li> <li><a href="http://support.blackboardcollaborate.com/ics/support/default.asp?deptID=8336&task=knowledge&questionID=58" target="_parent"><b>Zone Alarm (Zone Alarm Pro)</b></a></li> <li><a href="http://support.blackboardcollaborate.com/ics/support/default.asp?deptID=8336&task=knowledge&questionID=2379" target="_parent"><b>Kaspersky Security Suite</b></a></li> </ul> <h3>General Tips:</h3> <p>If your Personal Firewall is not listed in the above, here are a few general steps that you can use to configure your firewall.</p> <ul> <li>You will need to allow Java Web Start (javaws.exe) access to the internet — this may require both inbound and outbound connections.</li> <li>Web conferencing or Elluminate Live!may require access separately — you will need to allow this on both inbound and outbound connections as well.</li> <li>You may be prompted to allow IeEmbed access to the internet when conducting a Web Tour.</li> </ul> <p></p> <h3>Configuring your Personal Router</h3> <p>Since most routers (for both wireless and wired connections) are shipped with a firewall enabled, you may have to configure them to allow web conferencing or Elluminate Live! traffic through. You may need to do this by allowing access on the specified ports, allowing access to the previously specified application or allowing access to hosts listed below. Configuration differs between routers so we advise checking the manual the shipped with your router and using the following information as supplement.</p> <p></p> <p>Since Blackboard Collaborate uses dynamic server assignment, it is not possible to state in advance precisely which server will host a session. This means the IP Address is known only when the session actually starts. Therefore, you must ensure firewalls (and proxy systems) allow access to the entire set of Blackboard Collaborate servers using the following domains and IP Address ranges:</p> <p style="margin-left: 30px;"><b>NA-SAS (Domain = elluminate.com)</b></p> <p style="margin-left: 30px;"><b><span style="color: #ff0000;">Current IP Addresses:</span></b></p> <ul> <li><span style="color: #800080;">216.220.49.208 with netmask 255.255.255.240 (in CIDR notation: 216.220.49.208/28)</span></li> <li><span style="color: #800080;">208.98.242.128 with netmask 255.255.255.240 ( in CIDR notation: 208.98.242.128/26)</span></li> <li><span style="color: #800080;">65.110.166.160 with netmask 255.255.255.224 (in CIDR notation: 65.110.166.160/27)</span></li> <li><span style="color: #800080;">69.46.102.224 with netmask 255.255.255.224 (in CIDR notation: 69.46.102.224/27)</span></li> <li><span style="color: #800080;">69.196.229.247 with netmask 255.255.0.0 (in CIDR notation: 69.196.229.247/16)</span></li> <li><span style="color: #800080;">74.200.25.224 with netmask 255.255.255.224 (in CIDR notation 74.200.25.224/27)</span></li> <li><span style="color: #800080;">74.200.26.160 with netmask 255.255.255.224 (in CIDR notation 74.200.26.160/27)</span></li> </ul> <p style="margin-left: 30px;"><b><span style="color: #ff0000;">Additional IP Addresses to be added on March 2, 2013:</span></b></p> <ul> <li><span style="color: #800080;">69.196.224.0 with netmask 255.255.244.000 (in CIDR notation: 69.196.224.0/19)</span></li> </ul> <p style="margin-left: 30px;"><b>EU SAS (Doman = bb.collab.com)</b></p> <ul> <li><span style="color: #800080;">46.183.240.0 with netmask 255.255.252.000 (in CIDR notation: 46.183.240.0/22)</span></li> <li><span style="color: #800080;">46.183.244.0 with netmask 255.255.255.000 ( in CIDR notation: 46.183.244.0/24)</span></li> </ul> <p><span style="color: #800080;"></span> </p> <p>Enabling access to all of the address blocks listed above will reduce the impact of any configuration changes that Blackboard Collaborate might make.</p> <h3>Configure Ports</h3> <p>Please note that Blackboard Collaborate Web Conferencing connects on one of these TCP ports:</p> <ul> <li>80</li> <li>443</li> <li>2187</li> </ul> <p>Web Conferencing establishes a connection through these ports. Once this connection has been made it will remain open and transfer all communication through a proprietary protocol called the Collaborative Communication Framework (CCF), which is layered on a TCP transport protocol.</p> <p><b>Note for ELM users:</b> If you are using a Hosted ELM instance you must connect to web conferencing sessions on port 2187 since port 80 is reserved for webpage traffic.</p> <p>This is also true if you have installed your ELM server on the same machine as your Blackboard Collaborate web conferencing server because by default your ELM server is installed to listen for web traffic on port 80 and therefore can’t establish an web conferencing connection on that port.</p> <p><b>Note for Blackboard Collaborate Mobile users:</b> If you are using Blackboard Collaborate Mobile you <b>must</b> connect to web conferencing sessions on port 2187.</p> <h3>Configure Firewalls</h3> <p>Configure your network's firewall and web content filters to allow the download of both JNLP files (or content types) and Java application archive (JAR) files. Also configure users' client systems to allow the download, installation, and execution of Java network applications.</p> <h3>Additional Notes</h3> <ul> <li>Only users invited to a web conferencing session (those with a session link) may connect to a Blackboard Collaborate server.</li> <li>The connection to the server is always initiated from the client</li> <li>After connection, data is exchanged only between clients and the Blackboard Collaborate server. Data is never exchanged between clients.</li> </ul> <p>For more information, and access to a 24-hour Configuration Room you can use to test your ability to login to a Blackboard Collaborate session, please <a href="http://support.blackboardcollaborate.com/ics/support/default.asp?deptID=8336&task=knowledge&questionID=1473" target="_blank">click here</a>.</p> <p class="link_to_this">Link to this article: <a href="http://support.blackboardcollaborate.com/ics/support/default.asp?deptID=8336&task=knowledge&questionID=45" target="_blank">http://support.blackboardcollaborate.com/ics/support/default.asp?deptID=8336&task=knowledge&questionID=45</a></p> <p class="link_to_this"> </p> </div></p><h3>Alternate Questions/Keywords</h3><p>How do I configure my firewall for Elluminate Live!</p>
