Dropping traffic from external ip address

MarkThornton

I am struggling to get a working firewall rule to drop or reject traffic from an external ip address. My mail server keeps getting hammered by IP addresses it reports as being from Iran. I created a firewall rule at the top position but it isn't having any effect. I thought the system processed from the top down. What am I missing?

    Google couldnt help me find anything about a dead end nat. I will keep looking. As to the destination network, i have tried several things; the destination server address both internal and external and I tried the interface. Are you suggesting it should be the internal lan network object?
