Hi Oliver, 99 times out of 10, the reason for this is that the redirect URL is being resolved by ISA to the same IP that the client resolves the public URL to. Make sure ISA resolves the redirect URL to the upstream server. -----Original Message----- From: Oliver Locher [mailto:ol@xxxxxxxxxx] Sent: Monday, July 11, 2005 6:00 AM To: [ISAserver.org Discussion List] Subject: [isalist] Supporting Both Basic and Forms-based Authentication with a Single External IP Address and Web Listener http://www.ISAserver.org Hi I have implemented the listener concept as you can find under this url: http://www.isaserver.org/tutorials/2004pubowamobile.html But everytime I will connect to the external listerner via OWA or OMA/ActiveSync I will get an error message like this: 12206 The ISA Server detected a proxy chain loop. There is a problem with the configuration of the ISA Server routing policy. Please contact your server administrator. We use ISA Server 2004 Enterprise with two nodes.
