[4.9+][network blocker] CLOUDSTACK-9838: Allow ingress traffic between guest VMs via snat IPs This enables the firewall/mangle tables rules to ACCEPT instead of RETURN, which is the same behaviour as observed in ACS 4.5. By accepting the traffic, guest VMs will be able to communicate tcp traffic between each other over snat public IPs. This is a regression from ACS 4.5, observed in ACS 4.9.2.0.
