Hi guys, strange issue that we have now seen twice on two different clusters. After an HA failover, the standby firewall picked up and was allowing traffic, but then when it failed back (we have revert to higher priority set) the gateway then dropped the traffic against the clean-up rule. It wasn't first packet isn't syn or anything like that, it was new connections (we had testers trying) and the drop reason was hitting the drop all rule in last position the policy. The fix was to install policy and it started working immediately again.
The rules that were impacted were simple IP to IP rules. Anyone seen this before?
Gateways are R81.10 T45
