title: Configure squid on centos to only allow one ip
body: <p>I setup squid on centos 6.4 using a guide I found through google. I am using a VPS and connect to it from my home computer to browse anonymously and connect to an ftp server for work. It is working fine, however as of right now anyone can connect to the proxy. How do I limit it to only allow my home ip?</p>
  
  <p>Here is my config, </p>
  
  <pre><code>#
  # Recommended minimum configuration:
  #
  acl manager proto cache_object
  acl localhost src 127.0.0.1/32 ::1
  acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1
  
  # Example rule allowing access from your local networks.
  # Adapt to list your (internal) IP networks from where browsing
  # should be allowed
  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
  
  #
  # Recommended minimum Access Permission configuration:
  #
  # Only allow cachemgr access from localhost
  http_access allow manager localhost
  http_access deny manager
  http_access allow all
  http_access allow localnet
  
  # Deny requests to certain unsafe ports
  http_access deny !Safe_ports
  
  # Deny CONNECT to other than secure SSL ports
  http_access deny CONNECT !SSL_ports
  
  # We strongly recommend the following be uncommented to protect innocent
  # web applications running on the proxy server who think the only
  # one who can access services on "localhost" is a local user
  #http_access deny to_localhost
  
  #
  # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
  #
  
  # Example rule allowing access from your local networks.
  # Adapt localnet in the ACL section to list your (internal) IP networks
  # from where browsing should be allowed
  http_access allow localnet
  http_access allow localhost
  
  # And finally deny all other access to this proxy
  http_access deny all
  
  # Squid normally listens to port 3128
  http_port 0.0.0.0:3128
  
  # We recommend you to use at least the following line.
  hierarchy_stoplist cgi-bin ?
  
  # Uncomment and adjust the following to add a disk cache directory.
  #cache_dir ufs /var/spool/squid 100 16 256
  
  # Leave coredumps in the first cache dir
  coredump_dir /var/spool/squid
  
  # Add any of your own refresh_pattern entries above these.
  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
