Fixed an issue that occurred when two FQDNs were resolved to the same IP address and were configured as the same src/dst of the same rule. If one FQDN was later resolved to a different IP address, the IP address resolved for the second FQDN was also changed, which caused traffic with the original IP address to hit the incorrect rule.
