Hello,
I'm trying to migrate an old router from a physical machine to a KVM on a proxmox. There will be two proxmox machines in a cluster-based for high availability.
For the moment I have strange behaviour and I think it's something from the logic that I'm missing from.
I have lots of VLAN that there were added to the proxmox machine on an LACP port, the VLAN's are working great and the virtual machine can route the traffic. The only problem is that the traffic cannot be routed back to the host machine (proxmox) that is hosting the VM and I cannot access it anymore.
Setup:
LACP for Proxmox1 - VLAN 502 for management and others (trunk mode)
LACP for Proxmox2 - VLAN 502 for management and others (trunk mode)
The virtual machine is on Proxmox 2 and the network configuration on the host machine is:
The interface assigned to the router VM is vmbr1.
On the switch, I can see all the 3 mac addresses for vlan502 (proxmox1, proxmox2, router machine).
Nothing is reachable on vlan502, I cannot reach proxmox1, proxmox2. Everything else works fine.
Tcpdump on vmbr0 shows nothing except the arp requests and I can see the arp's from proxmox1-proxmox2, nothing from the VM is visible.
Disabling the VM network interface and activating the old router with vlan502 restores the issue.
Definitely, it's something that the VM from vmbr1 is not communicating back with the network on vlan502 but I cannot understand the logic as also proxmox1 is not responding back.
Is there something that I need to add to vmbr1? Should I add to vmbr0 bridge_ports vmbr1 (not sure if bridge in bridge will work
).
Thanks!
