Hi All, As I am fairly new to ISA I appologise in advance if this is common knowledge, I did a search but could not find much! The latest addition of ICQ - 2001b seems to be getting out past the current "Site and Content" rule that I have in place. This rule seemed to have no problems in blocking ver 2000b but alas I have a new version to contend with. As best as I can figure the new version is slipping by via port 443 (SSL). What I am looking for is away of blocking the login.icq.com url on port 443. By the way the proxy client is not an option in our current environment. Thanks in advance. - Dimiter -
