Configure multiple subnets on single NIC in Proxmox

I have a 1x4 sfp+ 10Gbe NIC in my host machine and 2 vlan subnets, 192.168.2.0 and 10.0.0.0, configured on my Cisco Nexus 5596UP switch. I have created 2 bridges in Proxmox, vmbr0 (IPv4: 10.0.0.3/24 Gateway: 10.0.0.1) on enp20s0f0 and vmbr1 (IPv4: 192.168.2.4/24 Gateway: not set) on enp20s0f1. The VLANs are configure on the Cisco switch, but I cannot ping or connect to either vmbr1 at 192.168.2.4 or my Home Assistant VM at 192.168.2.5. Any thoughts?

Edit: I had to remove vmbr1 because Proxmox would not let me access the web ui recently, though it was fine at first.

Where are you running the tests from?
Paste your Cisco vlan/trunk/eth config, and a detail of what interface is connected to what port on the switch.
How are you bridging the two VLANs?

It wouldn’t hurt if you shared a layout too.
