[WONTFIX] LAGG - VLAN - CARP not working

[romain]

This is the exactly the situation I test.

[vm, client]   -->  [master, vip] --> outside world
                           [slave, vip]   --> outside world

I didn't test the ping but the rest works (browsing internet, DNS resolution...).

Nope only the firewall are using CARP. There is no VRRP configured anywhere on my architecture

The thing is the arp resolution seems not working. The mac address associated to the VIP address stay  00-00-5e-00-01-01 on the VM as it does not receive any answer to it first arp request.

If I add manually the MAC address of the master network carp, everything is working.

I know that my setup is complicated but I can't undo everything and test it. I can't start from begining as I have some service in production. Sorry :-(

Does my switchs should be VRRP aware or I can use a basic switch ?

[romain]

I saw that there is 4 modes of load balancing in the Carp protocol.

Is there anyway that I can manage which mode is activated ? it seems to be activated by default on arp but for some environment ip or ip-stealth can be better.

Thank you

I have new news. Everything is okay on OPNsense.

I contacted the technical support of the network card and they compile me a new driver without these bug.

Thank again for your help !
