I imagine you could script this yourself if you really wanted. It would be work
But it would be a hole in auth to enable a backdoor based on CIDR range with the complexity of attacks these days, easy to get wrong. Very hard to get right.
So I doubt it?
Right. No biggie. Thanks!
What are you trying to achieve? I could propose alternatives like using a password manager like bitwarden that would autocomplete login info so login is less of a hassle. You can also use SSH to start/stop/list/etc. VMs so you could create a small local UI or shell script to automate the tasks using key based auth so you don't have to input login data.
I also don't think there's any reason for your proxmox web UI to be available outside your local lan or a VPN. Maybe I'm misunderstanding the question.
I don't want to have to enter password when I'm accessing my Proxmox admin when I'm home. That's it :)
