Any other ideas? >From what I understand UDP_DENIED means the ICP query can be denied due to the icp_access rules. I appear to have resolve the issue. Originally I had this: acl local_network src 192.168.0.0/16 icp_access allow local_network icp_access deny all Which *should* have worked right? Anyway I changed it to the following and now I am not seeing the errors: acl squid_peers src wp01.example.com wp02.example.com wp03.example.com icp_access allow squid_peers icp_access deny all Cheers, JLK
