Problems with the Internet on a VM

[bedman]

Installed proxmox 5.3
On the server 1 network card (enp11s0f1) with external ip 79.64 is included.
Created a Linux Bridge vmbr0.
Installed VM Cent OS 7.
I registered external ip address 78.79 in Cent OS settings.
And it turns out that's the thing.
If I specify "bridge-ports enp11s0f1" in the vmbr0 settings, then the main ip 79.64 (enp11s0f1) stops responding and 78.79 (vmbr0) starts pinging.
If I put "bridge-ports none", then vice versa, ip 79.64 (enp11s0f1) starts pinging, but 78.79 (vmbr0) stops working.
Tell me what to do.
Thank.

configure the external ip 79.64 on the 'vmbr0' not on the bridge-port enp11s0f1.

Configure ip 79.64 on vmbr0? What does it mean? Show an example, please.
What is wrong now?
Did not quite understand what to do

configure the external ip 79.64 on the 'vmbr0' not on the bridge-port enp11s0f1.

Sorry - what I meant was something like:

iface enp11s0f1 inet manual

auto vmbr0
iface vmbr0 inet static
       address xxx.yyy.79.64
       netmask 255.255.255.0
       gateway xxx.yyy.79.1
       bridge_ports enp11s0f1
       bridge_stp off
       bridge_fd 0

hope this helps!

This is fantastic, finally earned!
It is a pity that this is not configured automatically or not in the manual =)
I am very grateful to you! Have a good mood!
Thanks!

Glad it worked out! (Please mark the thread as SOLVED so that others know what to expect - Thanks!)

* the config I posted is pretty much the config you get from the PVE-Installer
* it is also the first example in our reference documentation (although I see that the network-config part there is a bit complex) - https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_network_configuration
