Hello all, I have what should be a very simple addition that I am trying to make to my squid.conf file. I must be overlooking something rather obvious and would appreciate it if someone would point me in the right direction. I am trying to make it so that I can allow access through the squid server to specific IP address (See the comment with all the ****s in my config file). So I added the necessary acl http_access commands and reloaded the system, but no luck. In fact I have been hacking away at this for several hours now and I am not making any progress. Any pointers would be greatly appreciated. Thanks, Ted I am running, SQUID-2.5.STABLE6 and have been for a few years. Here is my squid.conf (or very close to the live one anyway): hierarchy_stoplist cgi-bin ? acl QUERY urlpath_regex cgi-bin \? cache_access_log /var/log/squid/access.log cache_log /var/log/squid/cache.log cache_store_log /var/log/squid/store.log pid_filename /var/run/squid.pid auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 7 auth_param ntlm max_challenge_reuses 0 auth_param ntlm max_challenge_lifetime 20 minute auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 3 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hour refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 quick_abort_min -1 KB range_offset_limit -1 KB external_acl_type wbinfo_group_helper ttl=300 %LOGIN /usr/libexec/wbinfo_group.pl acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 563 acl Safe_ports port 80 acl Safe_ports port 21 acl Safe_ports port 443 563 acl Safe_ports port 70 acl Safe_ports port 210 acl Safe_ports port 1025-65535 acl Safe_ports port 280 acl Safe_ports port 488 acl Safe_ports port 591 acl Safe_ports port 777 acl CONNECT method CONNECT # acl Full_Internet_Access proxy_auth REQUIRED acl Allowed-Domains dstdomain .google.com acl Full_Internet_Access external wbinfo_group_helper Full_Internet_Access acl Blocked_Ad_Servers dstdomain .advertising.com acl Blocked_Webmail_Servers dstdomain .hotmail.com acl Webmail_Block_Bypass external wbinfo_group_helper Webmail_Block_Bypass # **************************** acl Allowed_Linux_Servers_To_Outside src 192.168.10.48/255.255.255.255 # acl Allowed_Servers srcdomain pcgalore.domain.ca. # **************************** acl Allowed_IPs dst 1.2.3.4 acl Blocked_Other_Servers .ebay.com no_cache deny QUERY http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow Allowed-Domains http_access allow Allowed_IPs http_access deny Blocked_Ad_Servers http_access allow Webmail_Block_Bypass http_access deny Blocked_Webmail_Servers http_access deny Blocked_Other_Servers http_access allow Allowed_Linux_Servers_To_Outside http_access allow Full_Internet_Access http_access deny all http_reply_access allow all icp_access allow all visible_hostname proxy cache_dir aufs /cache1 10000 30 256 cache_dir aufs /cache2 10000 30 256 cache_dir aufs /cache3 10000 30 256 cache_dir aufs /cache4 10000 30 256 cache_effective_user squid cache_effective_group squid cache_mem 150 MB http_port 80 http_port 3128 maximum_object_size 75 MB cache_replacement_policy heap LFUDA deny_info http://intranet/images/placeholder.gif Blocked_Ad_Servers
