Hi Albrecht

I see the SK but not applies, I try to explain 🙂

On windows when Harmony is working and the user connects to VPN whit cisco any connect can reach all internal resources whitout problem, for this I see wich Harmony and CIsco Any Connect creates a virtual NIC and set all paramters for works fine.

On MAC when Harmony is working and the user connects to Cisco Any Connect, the internet is down for a seconds, when the internet is restablish, I see a virtual Adapter for Cisco components but not for Harmony, in DNS settings of the physical NIC I see a 127.0.0.1 address whit this not is possible reach internal resources, if Harmony is shut down the DNS are set whit internal DNS IP 131.x.x.x and is posible reach all internal resources and works whitout problems

I opened a case but no received a usefull reponse about this behaivoir.

I had similar issue with another customer and turned out to be new OS version (Monterey), but worked on Catalina. You may wish to test it.

We are currently have this issues in our environment as well. Did you get any resolution? I've had a ticket open for about a month and they can't figure out the issue.
