Published servers should be configured as SecureNAT clients. Not mandatory but preferred and considered best practice. You can configure some published systems as a firewall client but that requires modifications to an .ini file.

Steve _____ From: William England Sent: Wed 29/01/2003 04:06 PM To: [ISAserver.org Discussion List] Subject: [isalist] Exchange 2000 and Firewall client http://www.ISAserver.org Hello everybody I have ISA on one machine and Exchange on another on the internal network. All incoming mail gets to ISA is scanned by GFI MailEssentials and MailSecurity then passed on to Exchange 2000. For out bound mails Exchange passed on to the ISA machine for scanning and sending out to the net. Can anyone explain why my Exchange only sends mail with the firewall client disabled? Do I need to use the Firewall client? Can someone tell me when I do and when I don't need the Firewall client?
