The WSUS remediation occurs over 443/80, and if you're proxying for that, either your proxy server would need to be intelligent enough to send that traffic to your WSUS servers, or you'll have to disable the proxy for the WSUS servers.</P><P></P><P>HTH,</P><P>Faisal</P><P>--</P><P>If you find this post helpful, please rate so others can find the answer easily</P></BODY></HTML> Fri, 12 Nov 2010 03:19:10 GMT https://community.cisco.com/t5/network-security/nac-and-wsus-workstations-with-proxy/m-p/1570105#M749867 Faisal Sehbai 2010-11-12T03:19:10Z
