Server 2003 RRAS Port Blocking issue

We have a Server 2003 system set up and have been experiencing issues with virus spam causing us to be blacklisted.  I added a second NIC to the server and set one up on a private IP range with the router ( and router at and our internal LAN is on (server).  I set RRAS to have a static route to to go through gateway at (so it forwards all traffic to the gateway).  The internet works like this, the DHCP gateway is set to the server NIC ( and everyone's internet works.

Now, I have gone to the NAT/Firewall section and have been trying to work with the INTERNET NIC, because it is the one with the translated #s and mappings next to it, so I assume that's the one to work with.  I have attempted all kinds of setup configurations, but when I go to View Mappings, they seem to not have taken effect.  I have tried various settings, and nothing seems to block the offending PCs.  

HOW do I set up static packet filter to BLOCK OUTBOUND attempts to send spam.  I have tried many many combinations of settings in the packet filter with no success. Even now, I have an outbound filter that states ANY traffic on destination port 25 is to be blocked.  I have another that says ANY traffic FROM IP address (an offending address) is to be blocked, but I still have plenty of mappings from that IP.

As of right now, I have inbound and outbound filters for the IP to ANY destination on ANY port, and I still have mappings for that IP.  Is there a configuration issue with my RRAS?  The only network card I show mappings on under NAT/Basic Firewall is my "internet" interface (the nic connected to the wan)

I found this very, very helpful to me when trying to hammer out the issues:

Well, after leaving it for a while with just an outbound filter on for port 25, it seems to work.  I guess you just have to leave it sit for a while?  I will go ahead and leave this thread open.  Anyone who wants points should leave some explanation, insight, or where I can get more info on blocking with RRAS

Well, unfortunately, yours was the only response I got.  I do appreciate it, it was good information.  I had hoped more people would join in and give information, but that's fine.
