3. I am configuring the ubuntu server on proxmox 8 via gui and setup
ipv4 and ipv6 manually with their subnet, ip and DHCP gateway.
a) I edited ipv4 first
b) I edited ipv6 second
Installed.
I was expecting that ipv4 and ipv6 will use their own dhcp server to
connect however this only set a single DHCP server routes default to the
Action done on b).
I am expecting if it should have looked like this as what is working for
me after manual editing the yaml file.
