Mutiple External Nics

[cccn714]

Hey everyone I'm sure this has been asked and answered but couldn't find a post on the subject.
I am new to Proxmox and running the latest version.

My Proxmox has 3 nics installed:
eth0: I am using for management, and it is used for the default vmbr0 and has a gateway assigned.
eth1: is connected to an external unmanaged switch for network 10.10.10.0/24 and vmbr1 is the bridge.
eth2: is connected to another external unmanaged switch for network 192.168.50.0/24 and vmbr2 is the bridge

the issue I am having is any vm created that I connect to vmbr1 or vmbr2 can't connect to the internet or anything outside the promox server. Traffic doesn't seem to route out of the proxmox server. Both networks 10.10.10.0/24 and 192.168.50.0/24 have internet access and physical devices connected to my switches can access the internet so i know something in the proxmox network configuration is not setup right.

I can't even ping each gateway 192.168.50.1 and 10.10.10.1 from the vm's.

So the question is how do I use mutiple nics and have my vm's to communicate out of proxmox on my 2 separate interfaces. Do I have to use VLANs for this?

Thanks

Please show your setup, not the GUI. the under laying files. Do you use SDN?

please see: /etc/network/interfaces (base config file) and files in /etc/network/interface.d/ (more network device related config files).
