VPN Cisco IPSec not working after Big Sur update
Tested on 2 x iMac, 1 x MacBookPro, each under OSX 11.0.1 (20B29).
VPN(Cisco IPSec) establishes a connection.
But no network traffic is possible - ping etc. is completely dead.
With OSX 10.15.7 VPN(Cisco IPSec) works without any problems.
Question: What did Apple change with Big Sur that IPSec no longer allows any data traffic?
