@ITEB18 The IP ranges on the firewall document are current. Regarding GoToMeeting V9, unless your account is somehow opted into the Beta program, you can uninstall this software to make sure it is not in use any longer. The IP ranges for GoToMeeting V9 should be the same as V8-- using IP ranges however, may require more maintenance than whitelisting domains.
Updated main post on 1/2/2019 to include a full list of LogMeIn Inc. products and services.
Update: 1/14/2019 We will be adding a new data center for the Sydney Australia region on 1/30/2019.
This new data center will improve the screen sharing experience for our customers in that region. GoToMeeting, GoToWebinar and GoToTraining customers (worldwide) who utilize screen sharing should refer to the optimal firewall configurations documentation if they have restricted firewall settings. Configure firewall settings according to these instructions.
