I run several honeypots on vmware.  Not sure if you have the budget for it
but vmware workstation is about $200.  You install the honeypot on a vmware
virtual machine and then you can setup a transparent linux bridge firewall
on another virtual machine and force all traffic to go through that.  At
that point you can control traffic from the host, do rate limiting, etc with
IPTABLES and/or snort_inline.

And after you have your compromised machine and have analyzed it you can
revert to a nice clean un-compromised copy with a single click of a button.

Subject: [Dshield] Windows Box Need To Filter Outgoing Port 445

Its been a good day for learning new things. I've setup a very small XP 
honeypot and had it compromised after 30 minutes. I've taken it down at the 
moment, but I'd like to put it back online with outgoing port 445 filtered, 
as the honeypot is now scanning on port 445. I am using a dialup connection.

What is the best Win XP program to filter only outgoing port 445?

Cheers.   Nem
