How can I undo qvm-prefs sys-whonix ip 10.152.152.10 back to default?

qvm-prefs -D sys-whonix ip

qvm-prefs sys-whonix ip 10.152.152.10 works great so far. Will test more. And call for testers.

But we couldn't just set that IP inside sys-whonix without touching dom0?

I am asking, because I am wondering how would we port existing and new users to be using this? Changing something for everyone in dom0 might be harder than if just a Whonix package upgrade could make the change.

No, qubes specifically enforce anti-spoofing firewall rules and VM is constrained to IP set in this property. Allowing VM to freely modify it would defeat the purpose.

There is https://github.com/QubesOS/qubes-core-admin-addon-whonix that can be used to set the IP.

Have you checked how it behaves with multiple Whonix Gateways? Isn't same IP a problem there?

Aren't these separated at the virtualizer level? Separate internal networks?

That would for sure be a problem. At worst non-functional or traffic
processed by the wrong gateway.
