I've upgraded two Macbooks and now a M1 iMac. The iMac seems to have broken DNS only on the built in eth interface. I can ping IPs (internal and external). DNS works fine when I switch to Wi-Fi. DNS works fine if I use a Belkin USB-C to eth adapter. I've tried reboots, deleting eth service and adding it back, I've tried alternate DNS server IPs. I've not gone as far as to start deleting network related plist files or whatever. I've also noticed post upgrade every app is asking for permissions to desktop, mic, etc. Messages logged me out. It's like a fresh install almost with nearly every app and service giving me an intro screen or asking for login or permissions. Any thoughts on how I might be able to fix this?

Dove in and upgraded two Macs today to beta 1. Unfortunately, it appears L2TP VPN is broken or something changed in the way it works. I can longer get a connection to any VPN concentrator I used previously. I tested with Cisco Anyconnect SSL VPN client and can connect to the same concentrators (as they're configured to accept L2TP or SSL clients). I also tested from my phone running iOS 16 beta and it still works for the L2TP connections. The Mac not working with L2TP VPN ppp.log shows this Fri Jun 10 19:18:52 2022 : L2TP connecting to server 'IP removed' (IP removed)... Fri Jun 10 19:18:52 2022 : IPSec connection started Fri Jun 10 19:18:52 2022 : IPSec phase 1 client started Fri Jun 10 19:19:02 2022 : IPSec connection failed Connecting a Mac successfully on 12.4 the log shows Fri Jun 10 19:12:33 2022 : L2TP connecting to server 'IP removed' (IP removed)...

But, now that it is broke and I need it for work I'm kinda screwed myself. Anyway, if anyone knows a way to fix this please let me know.
