This was resolved by disabling unbound from my OPNSense Firewall and using DNSMASQ instead. I am not sure what Unbound was doing to cause any issues.

I am running out of ideas on what the problem can be. I have 3 Virtual Machines (Windows Server 2019, and two RedHat 9 Servers) that are all connected to a bridged network (br0). Upon starting up any of the VM's I am able to ping from my desktop and get a response, after the 8th ping I get an error stating that "Destination host unreachable." I can reporduce this issue by turning off the network on the VM and re-enabling it, I will get 8 or so successful pings but then it will fail with "Destination host unreachable." Whats odd to me is that from any of the VM's I can ping my gateway and any other device on the network. This led me to believe that I had a firewall issue to start with, I disabled all software firewalls on the VM's and even disabled my firewall on the OPNSense Router. Things that I have tried so far: 1) Changing the Network Model 2) Creating a Separate Bridge and dedicated vhost 3) Refreshing the MAC Address 4) Setting up a static reservation for the MAC Address Current Network Topology ATT Gateway (IP Passthrough) --> OPNSense Router --> Ruckus Switch --> Dell Switch --> Unraid Server Gateway: 192.168.10.254/16 Unraid Network Settings Interface: eth0 Bonding: No Bridging: Yes Bridging Members: eth0 Network Protocol: IPv4 Only IPv4 Address: Automatic (I setup Static Reservation on the OPNSense Router) IPv4 Address: 192.168.50.30 IPv4 default gateway: 192.168.10.254 IPv4 DNS server assignment: Automatic Enable VLANs: No Routing Table: IPv4| default | 192.168.10.254 via br0 | 1075 IPv4 | 192.168.0.0/16 | br0 | 1075 Test VM Settings Network Source: br0 Network Model: virtio
