[SOLVED] CARP Cluster with VLAN Interfaces
«

Hi all,
I've extended my OPNsense Zotac Nano CI323 box with an additional one and want to setup a Carp Cluster.
The basic configuration of a Carp Cluster is clear because I found the information in the how to's.
On my master box I've configured 7 VLANs and corresponding interfaces assigned to the VLANs.
As far as I understood the Carp Cluster I have to configure for each VLAN one virtual IP.
Am I right with this because otherwise I will have duplicate IPs on my VLANs?
Looking forward to get some feedback.
Rainer.

Hi Rainer,
Did you have any trouble setting it up in the end? Anything you wish to share with others running into the same questions in the future?
Thank you,
Franco

Hi Franco,
I struggled a little bit at the beginning because as a have done the setup of the carp cluster I found out that my VLAN interfaces, the VLANs itself and all VLAN firewall rules from the master didn't appear on the backup node.
At this point I disabled the carp cluster and I've make a backup of my master configuration and restored this to the backup node. Then I changed the backup node name, IPs and so on. During this my backup node was only local connected to a notebook. I've done this because I don't want to make all the configuration again by hand.
After thinking of the further steps I created this topic.
In parallel I designed a configuration sheet for my VLAN configuration.
For my VLAN interfaces I configured on each node a dedicated IP address.
Then I created the corresponding virtual IPs in the Firewall-VirtualIs-Section.
For all IPs I created also a corresponding DNS record on the master box.
The next step was to connect the backup node again to my network.
Then I configured the Carp cluster again and done a reboot of each node.
After this my cluster was running fine without any problem.
I have now the exact VLAN configuration on each node.
I've done also some successfully failover tests by disconnecting the master/backup node from the network.
Best regards,
Rainer.
