I have been having an issue with Goto Meeting and SSL decryption since August 2010 and support/development has been very slow to resolve this issue. I am wondering if anyone else has a better work around or experience this issue. I am very frustrated that I can not use SSL decryption which was a key feature in the decision to purchase the Palo Alto appliance.
When I enable SSL Decryption, users who try to connect to a Goto Meeting session get the error message: Certificate Mismatch, they can not join a meeting. From my understanding this happens because the PaloAlto device uses the Goto Meeting Certificate to identify the Goto Meeting Application. Since it actually uses the Goto Meeting Certificate initially it later does not match the Certificate I created to decrypt the rest of the session, hence the Certificate Mismatch. It was ironic when support originally wanted to start a Goto Meeting to troubleshoot this.
Work arounds from support:
Put all IP addresses from Citrix in a SSL Decryption exception list for ssl decryption. This works for a little while until Citrix changes their IPs. This would work if I am allowed to do exceptions by URL instead of IP. Support came up with a way to learn the IPs but it requires users to keep trying until it finally works (this obviously is not a good solution, as users expect it to work the first time).
Work arounds that I tried:
I tried to make an SSL Decryption exception list for the URL categories belonging to Goto meeting but it still has the Certificate mismatch.
The feature that we have in place will automatically learn based on the hosted meeting. This obviously leaves a problem with the joiner of the meeting. At this time the only work around it to specify the IP addresses of GOTOMeetings sites. This is not a closed issue and it is being worked on by our developers.
