WAN letting traffic pass after deleting rule.
-
HA with separate ESXi hosts. HA is behind a firewall who's primary function is a router for VLANS. Continuous ping from an external source to an internal server on a VLAN. The ICMP packets hits the WAN interface on the primary and prevents the traffic from passing. Once the rule is added to allow ICMP from the source IP to the destination IP, it passes the traffic. Once the rule is Disabled or Deleted, that traffic continues to pass. If the primary is halted, the secondary doesn't pass the traffic until the rule is either added or reenabled. Once added or reenabled, the traffic passes again, but if the same rule is disabled or deleted on the secondary (the primary is still down), the inbound ICMP traffic continues to pass. (After creating/disabling/deleting the rule, the Apply Changes was clicked.) Version: 2.4.5-RELEASE-p1 (amd64) Intel(R) Xeon(R) Gold 5215 CPU @ 2.50GHz 2 CPUs: 2 package(s). Any ideas?
