FLEX500: Match default rule DNAT Packet, DROP
Options
Hello,
Can anybody explain that type of log like below:?
Match default rule DNAT Packet, DROP source: 192.168.100.12 --- dest.: 192.168.100.1
I haven't any NAT service to that subnet configured.
I have one NAT rule but destination address is in different subnet (different vlan)

Not sure how much it helps, but at least it can give you a little bit of insight to what the parts can be. You may also want to review the list of rules to see if any of them affect the NAT behaviour.1 -
Hi @tomeC,
Does your firewall have any interface binding subnet 192.168.100.X/24?
Moreover, please help to check if there are any physical cable attached between lan and wan switch.0 -
1. Yes, interface is in DMZ zone (base port also dmz)2. No, there is no physical cable between LAN and WAN

I found that CDR security service is a cause of it. After disabling there is no more problems. Actually that scope (192.168.100.X/24) belongs to vlan which is in Qarantine VLAN ID in CDR settings, but I cant remove it - can't set it to "none"?Can anybody explain this behaviour?0
