Proxmox 5.3 network setup help.

[jim.bond.9862]

Hello.
As I am slowly rebuilding my home setup
I am coming across a few challenges that buffle me a little.
I have a server with 4 nics.
I thought I can reserve one as host interface. And use 3 other for all my vm tragic.
All 4 nics are. Plugged in onto the same switch and on the network.
I have vmbr0 on one of the mics, my main host interface,
I also created a bond on 3 others and setup vmbr1 on that bond.
All connections are dhcp as I do ip reservations on my router.
I add both bridges to mine VMs.
All seams to work except I do not get up address on vmbr1 and I do not get ip address inside container on nic linked to vmbr1.
All connections are slow.

My question would be this....
Is there a better way to use all 4 host nics so I can get a connection redundancy and speed on host and VMs.?

You have to use fixed ip addresses for your host interfaces.

Aggregation is possible but has limits - have you read the bonding guide on Linux:
https://wiki.linuxfoundation.org/networking/bonding

If you have the same physical network on both bridges, why don't you use one?

LnxBil, Tim,
I have read the wiki. Both of them.
They describe the mechanics of how to set it up. I am trying to figure out what is the proper setup for me.

Tim. In an essence I do have fixed ip.
It is just not configured in proxmox but on my router. I run pfsense box for my router.
I do up reservation on it for specific MAC
So any machine will get the same ip every time but the hostname resolution is way better than static ip setup.

LnxBil. How would I set this up?
Do a bond on all 4 nics and put vmbr0 on it?
Add all 4 nics to vmbr0 as ports?
What about load balancing or redundancy?
In a bond I have the option. Hiw does it work on vmbr0?

Exactly. So your bridge has only one port, the bond device. Bonding mode is up to you or more precisely your hardware capabilities at the switch end.

Ok I have a netgear 48port switch.
It has managed mode but I use whatever the default settings were. Don't want to manage it. Essentially want to use it as plain switch. What are my option for bonding.
