Hi List, I just updated two carp/pfsync firewalls from 7.3 to 7.4. After updating the second box I see a massive increase in traffic on the sync interface. I now reproduced this with another pair of firewalls - same thing.
Both firewall have three physical interfaces: external, internal and sync. Sync interface is connected via ethernet cable directly. Syncinterface has an ip address. Configuration of hostname.pfsync0: syncdev em2 up The way I updated these boxes, lets call them primary and secondary: 1. update secondary to 7.4, including the change in hostname.pfsync0 2. change hostname.carp0 to promote to master - reboot 3. secondary is now master 4. update primary to 7.4 => traffic on syncif increases I tried so far - without any improvements: - reboot both machines after another - promote primary again - ifconfig pfsync0 down; pfctl -F states; ifconfig pfsync0 up I think they might see some kind of loop updating the states between each other. Could someone point me to how I could diagnose further? Kind Regards, Christian
