I've had an all-in-one proxmox box that hosts a pfsense image on KVM (virtio net) and a bunch of LXC containers that are my smaller micro services for my home network (e.g: plexmediaserver) and after a power loss I seem to have lost all my network settings.
Have been troubleshooting for a few days and have been unable to get Proxmox resume working with VLAN tags, not sure what else todo.
My firewall VM - pfsense
primary WAN (used to be virtio on vmbr2 int with a single NIC towards cable modem)
LAN (virtio interface to vmbr1)
DMZ (uses same as LAN interface but for traffic tagged vlan 666 802.1q)
LXC containers that are still not working:
network is set to vmbr1 vlan tag 666
but if I remove VLAN TAG of 666 to empty it gets an IP on my LAN (as expected) I am trying to restore the functionality for my vlan segment, I use proxmox to force all traffic to a certain vlan.
Behavior seen:
- DHCP requests are sent but never an offer or handshake seen.
- tried:
# tcpdump -i vmbr1v666 -n -e
config
root@pve:~# cat /proc/sys/net/ipv4/ip_forward
0
I am not sure what else to try, any ideas? No configuration had been changed. It looks like my bridge is not really bridging stuff anymore but the 'brctl show' indicates it still exists, is it possible to force proxmox to rebuild the entire bridging and network config to sorta reload everything?
