Nope; that's not true, either. SMTP Server Publishing gives you the SMTP Filter and (with ISA 2000 & 2004), the Message Screecher. This is far more capable than the "zealot technique". It's packet filters that are for the "openaport" fuuls and they only apply to services operating on the ISA itself. Is this an SBS deployment?

I want to say, at the end of the day, it is the packet filters. :) Server Publishing rules in ISA 2000 are just for all of the "hardware firewall" zealots. However, in appears as though I can only specify one source subnet per packet filter. ...D On 1/5/07, Danny <nocmonkey@xxxxxxxxx> wrote: Server publishing, I believe, but ISA 2000 is like MS02 security bulletins to me.
