Problem solved. Here's the answer (for the archives) # block all SMTP traffic from inside to out while letting the server # through ipfw add allow tcp from any to me 25 ipfw add allow tcp from me to any 25 ipfw add deny tcp from any to any dst-port 25 This prevents any host within the network from sending directly to an SMTP server outside the network. Thanks to "D J Hawkey Jr <hawkeyd@visi.com>" for helping me out with this. Cheers Tim -- Tim Aslat <tim@spyderweb.com.au> Spyderweb Consulting http://www.spyderweb.com.au Phone: +61 0401088479
