it strikes me that being a bit more proactive and blocking certain outgoing ports would be a good idea. I don't need any MS based traffic leaving the private network, so
suggest the 'block all' approach: just deny ALL to in/out, only allow the real needed ones, say: allow out 20-21,22,25,80,110 block all others for the IN rules you can build similar ones a FreeBSD box with statefull rules (either ipfw or ipfilter) will do the trick. --------------------------------------------------------------------------- Captus Networks Are you prepared for the next Sobig & Blaster? - Instantly Stop DoS/DDoS Attacks, Worms & Port Scans - Precisely Define and Implement Network Security - Automatically Control P2P, IM and Spam Traffic FIND OUT NOW - FREE Vulnerability Assessment Toolkit http://www.captusnetworks.com/ads/42.htm ----------------------------------------------------------------------------
