VPN (Cisco IPSec)
Since the update to Big Sur Mac OS 11.0.1 VPN Cisco IPSec does not work anymore.
My VPN services created on the default system VPN Type Cisco IPSec still do connect, but afterwards there is no IP traffic possible. Not even pings to IP addresses are possible.
I've looked into potential firewall issues, re-created the services on Big Sur and checked from Catalina and iOS where the VPN entries are still working flawlessly.
Any ideas?
