Hi all, Before upgrade from OpenBSD 6.7 to OpenBSD 6.8, my pair firewalls was using carp in IP balance mode without problems from several months. These firewalls are installed in a RHEL 8.2 (fully patched) KVM host.
After upgrading to OpenBSD 6.8, carp ip balance mode doesn’t works. I have tested reconfiguring balance mode for ip-stealth and ip-unicast also and the result is always the same: network packets are not processed by firewalls. But if I configure CARP using “the simple configuration” and one node is master and the other is backup all it is working without problems. Since the configuration is exactly the same for version 6.8 as it was for version 6.7, could there be some kind of problem with the virtio driver on the network interfaces in version 6.8? Regards, C. L. Martinez
