On your version of squid you block ports this way:

Code:
acl Bad_ports port 1-79
acl Bad_ports port 81-442
acl Bad_ports port 444-45000
http_access_deny Bad_ports   # 80 & 443 all else from 1-45000 blocked

NAME
squid_unix_group - Squid UNIX Group external_acl helper SYNOPSIS
squid_unix_group [-g groupname] [-g groupname...] [-p] [-s] DESCRIPTION
This helper allows Squid to base access controls on users memberships in UNIX groups. -g groupname Specifies a group name to match. -p Also match the users primary group from /etc/passwd -s Strip NT domain name component from user names (/ or separated) EXAMPLES
This squid.conf example defines two Squid acls. usergroup1 matches users in group1, and usergroup2 matches users in group2 or group3 external_acl_type unix_group %LOGIN /usr/local/squid/libexec/squid_unix_group -p acl usergroup1 external unix_group group1 acl usergroup2 external unix_group group2 group3 NOTES
By default up to 11 groups can be matched in one acl (including commandline specified groups). This limit is defined by MAX_GROUPS in the source code. AUTHOR
