Hi, I have set up a few ISA servers in integrated mode with two NICs and using it as the firewall. However, in this job, I am setting up ISA as a stand-allone proxy for a web filtering app, as we have plenty of other firewalls etc. I have installed ISA in firewall mode. I have set up the routing rule to forward requests to another proxy (i.e, proxy chaining). In the web access policy I have just left the default of allow all requests. Nothing has been changed, no web filter has been installed yet. Have applied ISA 2000 SP2. However, when I use the proxy in my browser, I get the following: HTTP 502 Proxy Error - The ISA Server denies the specified Uniform Resource Locator (URL). (12202) This is just going to a simple site like www.google.com. Any suggestions? I have read a similar problem in the faq, however, I don't believe it relates to this setup. Thanks. Andrew. ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
