Hi David, But then you lose out on the HTTP filtering done at the firewall if you don't use SSL to SSL bridging. The ISA firewall is an "approved" man in the middle, so its OK. Better to have an approved man in the middle then no man at all who inspects the traffic before the attack hits the SSL site. Thanks!

SSL bridging might downgrade this protection/feature of SSL we getting. My general advice is to enable only SSL sites you trust and disable rest of them as it might be security wormhole. Another approach is to check certificates of SSL sites accessed via ISA server (possible without SSL bridging) Regards DavidF -----Original Message----- From: Thomas W Shinder [mailto:tshinder@xxxxxxxxxxx] Sent: Wednesday, May 04, 2005 4:15 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: OWA Publishing http://www.ISAserver.org Hi Jim, There's got to be a way to do this. That's one of the major coolnesses of SSL to SSL bridging.
