I've had another look at this patch series and I think I found the reason for the issue(s) I encountered during my testing. One issue is related to the new IP forwarding settings. It seems like they are not applying. I've looked at the ifquery output after creating a QinQ / VLAN zone with DHCP enabled: { "name": "qinq5", "auto": true, "config": { "bridge-ports": "z_qinq5.456", "bridge-stp": "no", "bridge-fd": "0", "ip-forward": "on", "address": "172.16.5.1/32" }, "config_status": { "bridge-ports": "pass", "bridge-stp": "pass", "bridge-fd": "pass", "ip-forward": "fail", "address": "pass" }, "status": "fail" }, { "name": "vlan4", "auto": true, "config": { "bridge-ports": "ln_vlan4", "bridge-stp": "no", "bridge-fd": "0", "ip-forward": "on", "address": "172.16.4.1/32" }, "config_status": { "bridge-ports": "pass", "bridge-stp": "pass", "bridge-fd": "pass", "ip-forward": "fail", "address": "pass" }, "status": "fail" }, It seems like the ip-forward settings do not get applied and therefore the command 'fails'. The bridges are up and working but IP forwarding is enabled: root@hoan-02:~# cat /proc/sys/net/ipv4/conf/vlan4/forwarding 1 root@hoan-02:~# cat /proc/sys/net/ipv4/conf/qinq5/forwarding 1 The other issue was using QinQ zone with a bridge that has no bridge port configured and is not vlan-aware. In that case status is checking for the existence of the sv_ interface but it doesn't exist since there isn't a bridge port. This is also occuring without this patch, so no show stopper here imo. > It just miss the ip for dhcpserver different than gateway for ipv6 > handling for vlan/qinq/vxlan, but it should be easy to implement. > > Also, for ipv6 in vrf, it need a patch for dnsmasq, so I think this > will need to proxmox dnsmasq package version.
