I'd swear the ISA server is the world's most difficult firewall to configure
since MS decided to invent their own wording and functions that have
no resemblance to anything else in the real world. Worked with it on
one project (and have had to properly config many different vendors
firewalls), and decided to replace it with a real fw.

Their terminology is so bad that even a wild guess will lead to open
holes that you'd never guess were open. Replace it with something that
is sip aware. A $40 linksys can probably do a better job.
