Hi,

VM dot not receive IP from DHCP server running in LXC.

No FW, no iptables, no ebtables, all policies on ACCEPT, (both in LXC & Proxmox VE host).

The DHCP server gets the requests, but the VM seems not to receive them.

The only specificity: they are both in the same tagged VLAN 66. Vlan (un)tagging is made by Proxmox VE for both servers, on top of the default Linux bridge. But I guess this has nothing to do with the problem.

Logs from the DHCP server running on a haproxy LXC:

Code:
root@haproxy:~# tail /var/log/syslog -n 10

# And yes, there's a static lease for the VM:
root@haproxy:~# grep 192.168.66.75 /etc/udhcpd.conf
static_lease B2:84:3E:84:C9:33 192.168.66.75 # bootstrap
root@haproxy:~#



Do you have any idea ?
