Hi Rob, You can configure hierarchical caching and Firewall chaining with the upstream ISA Server. You need to use a Routing Rule for all requests for the hierarchical caching, but you can configure the Firewall chaining in the Firewall Routing Properties dialog box. You might need a password from your ISP. Try it out and if it does require a password, the Event Log will let you know :-) HTH, Tom www.isaserver.org/shinder -----Original Message----- From: Rob [mailto:rob@xxxxxxxxxxxxxxxxxx] Sent: Monday, August 12, 2002 3:31 PM To: [ISAserver.org Discussion List] Subject: [isalist] My ISP is using also ISAserver, how to configure my isaserver? http://www.ISAserver.org My networkconfiguration: (publicip)-router---(externalip)-ISAserver-(internalip)--my network with a mail and a webserver.
