I've had this happen also it seems that isa doesn't bypass proxy for local ip address only if browsing by machine name. so if the firewall client is forcing the machine to go through the proxy for the local loop back it is no longer local. You need to force isa to bypass the proxy for that address. _____ From: Eric Poole [mailto:EPoole@xxxxxxxxxxxxxxxxxxxx] Sent: Friday, January 13, 2006 10:15 AM To: [ISAserver.org Discussion List] Subject: [isalist] ISA 2004 blocking XP local loopback http://www.ISAserver.org Ok, I've been looking for the answer to this for about 45min. Why would ISA 2004 block a workstation from getting to 127.0.0.1? Same workstation going through ISA 2000 is able to access it's local loopback. Someone enlighten me please! _______________________________________________ Eric Poole, CISSP Senior Information Security Analyst HYPERLINK "http://communitymedical.org/"Community Medical Centers 1140 "T" Street, Fresno, California 93721 559-459-6784 (phone) 559-459-2045 (fax) ------------------------------------------------------- WARNING/CONFIDENTIAL: ------------------------------------------------------- This email, including attachments, may contain information that is privileged, confidential, and/or exempt from disclosure under applicable law (including, but not limited to, protected health information).
