Thanks guys, but my problem is getting outbound connections to other smpt 
servers.  I am testing by telnetting to another host on port 25.  I am not 
getting connected from one particuliar machine only, and it has no selinux 
running.  I have another windoze box that this does work for.  This happened 
after I created a nat rule, which I've since removed.  I am not sure if 
perhaps a remnant of this rule is hosing me somehow, which is why I need to 
know how to clean nat cache or something else.

Thanks all,
