    [SOLVED] Q-in-Q Support on Hetzner Dedicated Switch

    Well your config also seems quite fancy to me ^^. Well im now using a MESH network based on RSTP and 10 Gbit on SFP+ which is working very very well with quite less config and I could potentialy extend by more hosts at any time, have a look at this: First node: auto vmbr4 iface vmbr4 inet...

    [SOLVED] Q-in-Q Support on Hetzner Dedicated Switch

    Hello, I've got a small setup at Hetzner with a dedicated 10 Gbit/S SFP+ Switch (EdgeSwitch 16 XG) to interconnect my Hosts privatly. The switch is also 802.1q capable but sadly im only able to make Q-In-Q working between 2 hosts and not three as i have to. This is how my config looks like...

    VXLAN Multitenant

    Good Moring, my idea was to put all tenants onto the same vmbr and the same vxlan and only do the seperation by a VLAN-tag at the ProxMox GUI. Currently i'm not able to use this feature even if i set vlan_aware to yes at the vmbr device (Linux Bridge). Currently i have a seperated vxlan with no...

    Privat Networking - Ein Ding der Unmöglichkeit

    Hallo, ich bin jetzt schon seit über 10 std. dran zwischen meinen 3 nodes eine OVS Bridge zu konfigurieren. ZIel ist es das ich meinen VM's nur noch ein VLAN-tag zuweisen muss damit die Kommunikation funktioniert. Aber offenbar scheint der Private Switch den Hetzner anbietet ein reiner Layer2...

    Hetzner vswitch and Proxmox

    Just to make things clear here. In general it's not a good idea to have the public bandwidth, Corosync, Privat VM network etc etc. running all on a single Physical NIC with VLANs as this can lead to time-out's, fancying on high load or a other behaviours. If you have around 30-40€ more to spend...

    Hetzner vswitch and Proxmox

    Actually the most simply way to add a VLAN based Public routed Subnet like a /28 you can buy additionally for your vSwitch are those lines: auto lo iface lo inet loopback iface lo inet6 loopback auto enp35s0 iface enp35s0 inet static address netmask...

    Seit update auf 4.15.18-4-pve kein OVS routing mehr möglich

    Konnte das Problem endlich lösen. War aber alles irgendwie höchst seltsam. Hab die OVS brücke wieder abgerissen und eine Linux bridge mit vlan aware genommen. funktioniert bis dato ganz gut. Ist ja nur ein lokaler host ^^

    Seit update auf 4.15.18-4-pve kein OVS routing mehr möglich

    Hallo, ich musste gestern leider sehr leidsam feststellen das ich nach dem update auf den Kernel 4.15.18-4-pve kein routing mehr mittels OVS/VLAN abgebildet bekomme. Es wird schlechtweg nichts kommuniziert. Alles steht zwar auf grün in den Logs aber einen ping bekomme ich nicht durch. Geändert...
