Unable to SSH with PuTTY with AnyConnect VPN through an Orbi 960

This issue was resolved without any action from me or support.

I had tried connecting with PuTTy about a dozen times before and it didn't work. When I was experiencing the SSH failure, other things seemed to work fine while connected to the VPN. For example I could connect to websites just fine. Then while explaining the problem on the phone to Netgear Support, I tried SSH with PuTTy again and it worked. There was no setting change. There was nothing that Netgear Support did. I didn't change anything between the last failed attempts and successful attempt to SSH. I didn't even reconnect to the router or internet. I simply retried in PuTTY and it worked when just a few minutes before it had not.

My only guess is that there is something on my employer's network that was blocking SSH at first but then started allowing the connection. I never called my work IT Support so I assume whatever change happened through some automated process, but it must have taken at least a couple hours. Also to note is that my first SSH attempts were made about 12 hours after I had replaced my old Netgear router with my new Orbi 960 router. It seems to me that it took my failed SSH attempts to kick off the automated process that opened up the ability for me to SSH.

I have been connecting with SSH to my employer's VPN without any trouble since that first day.
