Whoops! Meant for my response to go to the message board for anyone else having this issue. Henrik, your idea worked perfectly. I thing I found was if I used multiple variables (chapman1 chapman2 chapman3 where each variable is an acl representing a subnet), I couldn't combine them on 1 line. "Snmp_access allow chapmansnmp chapman1 chapman2 chapman3" would not work. I had to give each variable a separate line: "snmp-access allow chapmansnmp chapman1" "snmp-access allow chapmansnmp chapman2" "snmp-access allow chapmansnmp chapman3" And then it worked like a charm.

Squid access rules has an implicity inverse of the last rule, i.e. the above is implicit followed by snmp_access allow all And says allow anyone to query for SNMP, except that only chapman1 is allowed to use the public snmp community. Any other community is ok for anyone to use, just not public. You probably want snmp_access allow chapmansnmp chapman1 which gets implicitly followed by snmp_access deny all Regards Henrik
