This page covers information involving the servers used for our GoTo products (GoToMeeting, GoToWebinar, GoToTraining, GoToAssist, GoToMyPC, and OpenVoice). Also see Whitelisting and LogMeIn for additional information on our other LogMeIn products. (updated 11/15/2017)
Our GoTo products are configured to work through outbound TCP ports 8200, 443 and 80, as well as UDP ports 8200 and 1853. Our products do not require any inbound connections. Outbound TCP port 443 is required in all cases. Connections via outbound TCP port 8200 are optimal for in-session communication, although TCP ports 443 and 80 can also be used. Optimal audio and video require that the UDP ports also be open.
Integrated Voice over IP (VoIP) connections are configured to work outbound through UDP port 8200. Integrated webcam video support is configured through UDP port 1853.
For InRoom Link video conference systems, configure your corporate firewall to enable the following send ports - 1720 TCP, 3000-4000 TCP, and 3000-4000 UDP. You can keep these ports closed when you are not using InRoom Link.
For most firewall or proxy systems, we recommend specifying a whitelist of DNS names for GoTo services so outbound connections can be made. The list of GoTo domains currently includes (but is not limited to) the following:
|*.assist.com||Product domain used by GoToAssist|
Note: This will soon change to *.filestackapi.com.
|*.citrixonline.com||Corporate domain used by multiple GoTo products (until 12/4/17)|

Important Note: Use of IP ranges instead of domain names for the firewall configuration are discouraged unless absolutely necessary because our IP ranges and those of our provider networks need to be periodically audited and modified, creating additional maintenance for your network. These changes are necessary to continue to provide the maximum performance for our GoTo products. Maintenance and failover events may cause you to connect to servers within any of the ranges.
If your firewall includes a content or application data scanning filter, this may cause blocking or latency, which would be indicated in the log files for the filter. To address this problem, verify the domains or IP ranges will not be scanned or filtered by specifying exception domains or IP ranges that will not be filtered. If your security policy requires you to specify explicit domain or IP ranges, then configure your firewall exceptions for outbound TCP ports 8200, 443 and 80, as well as UDP ports 8200 and 1853 for the LogMeIn domains or IP ranges, including those of our provider networks given below.

We scale our services into third-party cloud and carrier networks for improved performance. To ensure continuous up-time, we also maintain data centers in the following regions:

Our software will test all 3 ports and use which ever allows outbound communication.
@james2484 GoToMeeting, GoToWebinar and GoToTraining do not have a file transfer feature. For the Proxy you maybe asked to provide your credentials before our sofware will be allowed to connect, we also have a Connection Wizard that can be run on Windows PCs to trigger this if needed.
I would recommend starting with our System Check page here: https://support.logmeininc.com/gotowebinar/system-check-attendee There is a test session that you can try to join to test out the flow. You can download and run our Connnection Wizard from here: https://support.logmeininc.com/article/g2m050025
Is it possible to join a test session from the G2M setup MSI multi user installer? We use this in conjucntion with the GoToMeetingMultiUserOpener.
We have a relatively high secuirty environment, and the installed application doesn't seem to be running.

for the test, it seems to be trying to download a component? Surely it shouldn't be trying to use this location?
Yes, we do attempt to install the GoToMeeting endpoint through the AppData folder.
To join a test session, we have this page available: GoToMeeting Test Session
During our testing, we’ve found that the G2M multi-client makes connections to *.expertcity.com as LocalSystem. This only occurs during live webinars, not pre-recorded ones.
As a result, we’ve had to whitelist the URL above on a per machine basis, which is a bit of a management headache.
Moving forward, we’d like to make this a global exception, but we’re unwilling to do so without understanding exactly what is going on here behind the scenes.
Cna you please clarify?
