Hi all I have the following situation, I have a client behind my box running exchange, and they are getting spammed to death, I want to disallow all incoming traffic to their box, but allow incoming traffic from their secondries only, the secondries are not getting spammed at this moment. I am running a ipfw / natd combination My default ruleset is allow all I run the command ipfw add allow 200 tcp from 196.x.x.x to 196.x.x.y 25 and it effectivly blocks everything coming from anywhere even although I have just allowed it, if I remove the rule, it works fine again. If I run the rule ipfw add 200 deny tcp from not 196.x.x.x to 196.x.x.y 25 it works on the port, but blocks all other traffic which is not what I had in mind. What am I overlooking here.
