Finally decided to bite the bullet and upgrade 7.9.2 -> 7.10. PPPoE WAN and IKE2 VPN work as before and CPU usage on old CRS112 switch seems to have gone down a little bit (Dude shows the change 11% -> 8-9%). DynDNS seems to work OK. As I have OpenVPN deployed only on v6 then I can not tell anything...

我s there any way to check if all this works with Monterey? I have IKE2 VPN setup that has migrated from 6.49.x up to current 7.9 and all still works, but I have Mac with Monterey with no way to upgrade to Ventura.

Short answer: Yes; but I do not know the ''local" part in your syntax; i've used "127.0.0.1"
