Hi Peter, Are you trying to publish a Web site using a unihomed ISA Server? If so, check out my article on this subject over at www.isaserver.org/shinder Also, NEVER use IP addresses in your destination sets for Web Publsihing Rules. HTH, Tom Thomas W Shinder www.isaserver.org/shinder ISA Server and Beyond: http://tinyurl.com/1jq1 Configuring ISA Server: http://tinyurl.com/1llp -----Original Message----- From: Peter [mailto:pleeuwen@xxxxxxxxxxxxx] Sent: Monday, March 24, 2003 4:27 AM To: [ISAserver.org Discussion List] Subject: [isalist] Webserver publishing on caching only ISA http://www.ISAserver.org Second try, did not get any response on the first one and I really could use some help on this one. Please...... I'm trying to setup webserver publishing through a caching only ISA server, situated behind a PIX firewall. Currently a MS Proxy 2 server is handling this and this works well, however if I try to do a similar setup on ISA I keep getting the HTTP 407 Proxy Authentication Required (12209) Setup is as follows: Pix does a mapping from the external IP (194.x.x.x) to an internal IP (172.x.x.x) Unihomed ISA server has (172.x.x.x) as second IP number on the network interface. This (172.x.x.x) is configured on the ISA as listener for incoming web requests on port 80, no authentication required. Destination set created 194.x.x.x, path: /test/* Web publishing rule created, using above destination set to point to an internal IIS server, http://webserver/test, anonymous access allowed. When connecting from the Internet to http://194.x.x.x/test, I get the HTTP 407 error from the ISA server that's handling the web publishing. What am I missing here, or can't this be done like this ? tia, Peter ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Exchange Server Resource Site: http://www.msexchange.org/ Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
