It seem like i missing so many reply, Sorry for all. I try to reproduce everything about what I did in this reply. Currently, I use newer compile version Squid (3.5.12), see wiki, it should support arp acl originally, following is copy from WIKI. > The arp ACL requires the special configure option --enable-arp-acl in > Squid-3.1 and older, for newer Squid versions EUI-48 (aka MAC address) > support is enabled by default.

So, I think squid arp acl support is not the key. following is my whole config worked for CentOS 7, my need is connection to Squid server with my own laptop(with MAC address), no password is need. following is my network info, hope can help. my laptop is connection to internet through a old WIFI router. when I run traceroute in my laptop with WIFI conn, can not found any useful info. traceroute to MY_VPS_IP (MY_VPS_IP), 30 hops max, 60 byte packets 1 localhost (192.168.1.1) 2.017 ms 3.294 ms 3.549 mspp 2 MY_VPS_IP (MY_VPS_IP) 101.182 ms !X 101.965 ms !X 104.812 ms !p unless I connection my laptop directly to router with wired conn, can output meaningful route infomation. ------------------------- config begin ------------------------------ debug_options 11,2 auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid/squid.passwd auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hours auth_param basic casesensitive on acl localnet src 10.0.0.0/8 # RFC1918 possible internal network acl localnet src 172.16.0.0/12 # RFC1918 possible internal network acl localnet src 192.168.0.0/16 # RFC1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT acl proxy_ports localport 8087 # http proxy port http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localhost manager http_access deny manager acl advance_users arp MY_LAPTOP_MAC_ADDRESS http_access allow advance_users proxy_ports acl superuser proxy_auth zw963 http_access allow superuser proxy_ports acl authorized_users proxy_auth REQUIRED acl over_conn_limit maxconn 3 http_access deny over_conn_limit authorized_users http_access allow authorized_users proxy_ports http_access allow localnet http_access allow localhost http_access deny all https_port 8087 cert=/etc/squid/cert.pem key=/etc/squid/key.pem cache_effective_user squid cache_effective_group squid visible_hostname squid.proxy cache_mgr MY_EMAIL_ADDRESS cache_mem 64 MB cache_dir ufs /var/spool/squid 256 16 256 coredump_dir /var/spool/squid maximum_object_size 512 KB maximum_object_size_in_memory 64 KB cache_swap_high 95 cache_swap_low 80 cache_store_log none cache_log /var/log/squid/cache.log cache_access_log /var/log/squid/access.log logformat combined %>a %ui %un [%tl] "%rm %ru HTTP/%rv" %>Hs %<st "%{Referer}>h" "%{User-Agent}>h" %Ss:%Sh access_log /var/log/squid/access.log combined forwarded_for off logfile_rotate 60 refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 ------------------ config end --------------------- When I use w3m connection to google, w3m tell me user/password is need. following is squid log: ==================================== log begin ===================================== ==> /var/log/squid/cache.log <== 2016/01/13 14:19:07.952 kid1| 11,2| client_side.cc(2345) parseHttpRequest: HTTP Client local=*** remote=*** FD 14 flags=1 2016/01/13 14:19:07.952 kid1| 11,2| client_side.cc(2346) parseHttpRequest: HTTP Client REQUEST: --------- GET http://www.google.com/ HTTP/1.0 User-Agent: w3m/0.5.3+debian-15 Accept: text/html, text/*;q=0.5, image/*, application/*, video/*, audio/*, x-scheme-handler/*, x-content/*, misc/*, inode/* Accept-Encoding: gzip, compress, bzip, bzip2, deflate Accept-Language: en;q=1.0 Host: www.google.com ---------- 2016/01/13 14:19:07.953 kid1| 11,2| client_side.cc(1391) sendStartOfMessage: HTTP Client local=***** remote=***** FD 14 flags=1 2016/01/13 14:19:07.953 kid1| 11,2| client_side.cc(1392) sendStartOfMessage: HTTP Client REPLY: --------- HTTP/1.1 407 Proxy Authentication Required Server: squid/3.5.12 Mime-Version: 1.0 Date: Wed, 13 Jan 2016 14:19:07 GMT Content-Type: text/html;charset=utf-8 Content-Length: 3704 X-Squid-Error: ERR_CACHE_ACCESS_DENIED 0 Vary: Accept-Language Content-Language: en Proxy-Authenticate: Basic realm="Squid proxy-caching web server" X-Cache: MISS from squid.proxy Via: 1.1 squid.proxy (squid/3.5.12) Connection: close ==> /var/log/squid/access.log <== 1452694747.953 1 60.221.132.137 TCP_DENIED/407 4130 GET http://www.google.com/ -
