Subject:   possible to block one address on all ports?
Message-ID:  <>

 I have what I hope is a simple question that I /hope/ has a simple
option. Here's my scenario; My current filtering is done on an application/
service level. While I'm anxious to migrate this to IPFW, I'm don't yet
have the time available that will be required. But I have a situation that
requires the need to drop any, and all requests from one single IP address.
So I thought I might seize this situation as an opportunity to "get my
feet wet" with IPFW. So here's my question;
Is it possible for me to use IPFW without altering any traffic - that is;
nothing changes on incoming/outgoing EXCEPT where this /evil/ IP is
Or, can I start IPFW, and use it to ONLY drop all requests from this
/evil/ IP
no matter which ports that IP makes a request on?
I can? Can/would anyone be willing to tell me how?
Apologies in advance, I realize this is pretty "ground level stuff". But I
feel if I could get a good start, getting up to speed from there will be a
greatly shortened learning curve.

Thank you for all your time and consideration.
