Problem adding additional IPS

[iinfotecnica]

Hello, I'm new to Debian and I'm having a lot of difficulty adding additional IPS to the system.
I've tried several times to form it and all without success.
However, I found something strange on another one I had added and it worked, but on this other new server it doesn't work at all.

The configuration would be to use proxmox if anyone could help.

On the other server I used something like

Code: Select all

 auto lo
iface lo inet loopback

auto eno1
iface eno1 inet manual

auto eno2
iface eno2 inet manual

iface eno1 inet6 manual

auto vmbr0
iface vmbr0 inet static
	address 192.9.90.72/27
	gateway 192.9.90.70
	bridge-ports eno1
	bridge-stp off
	bridge-fd 0
	up ip route add 192.9.90.73/32 dev vmbr0

#e.g. 2001:db8::3, should not be the same as on enp1s0/eth0

iface vmbr0 inet6 static
	address 2a01:458:851:31bc::2/64
	gateway fe80::1
	up ip -6 route add 2a01:458:851:31bc::/64 dev vmbr0
 

With the same example above, it works well on one of my servers, but on this new server it doesn't work.

In fact, I need a Bridge network to adjust next time via Mac

If anyone can give any advice

Hello.
Is it a typo in the beginning of the file? I.e. space character before "auto lo"?
How exactly can you detect, that it does not work?
Are there any errors or issues in system journal related to networking?

What does "it doesn't work" mean exactly here? What specific command did you run and how did it fail?
