Just got Proxmox up and running. I have a Dell Precision T7920 with an integrated dual Gbe NIC. Right now I only have one port plugged in to my lan - 192.168.74.x/24. I have a bridge setup - vmbr0 - and have each of my vm's assigned to that. The bridge is configured with a local ip: 192.168.74.30/24 --- I have the three vm's setup with 192.168.74.31/24, .32/24, and .33/24 respectively. I do not have an IP setup on the port itself (only the bridge).
It would seem the bridge isn't responding to ARP requests for the 3rd 192.168.74.33 address. I can ping between all the hosts located on the bridge, however the .33 host can not ping anything outside or be pinged - the bridge itself and the two other IPs can be pinged to and from other hosts on the network. When you try to ping the .33 vm from outside, it will register that MAC in the .33 VM's ARP table, but not vice versa.
Any ideas on what could possibly be wrong with this seemingly simple setup. Side note - I killed the .31 and .33 hosts at one point, then rebuilt .33 and it started working, but .31 would then do the same thing as .33 before. It seems like for some reason I'm being limited to two functional IPs on the bridge (plus the bridge's IP).
Below is /etc/network/interfaces
