I'm using Squid and I want to know how to make a specific IP range of allowed connections, I use this

acl permittedips src

http_access allow permittedips

But I want to make an range that allows from 70.*.*.* to 90.*.*.*. How can I do this the easiest way?

You can use CIDR notation to signify this in the ACL for squid. You would want:

acl permittedips src
acl permittedips src

More information on CIDR:


  • This doesn't seem to work? My IP is 86.132.x.x and I can't connect to squid, it works if I put my oringinal IP address, but I want to specify the range BETWEEN 70.*.*.* to 90.*.*.*.

  • Oh, I missed the 'to' part. You really can't do that easily with CIDR, you'd be best off adding 20 rows one for 70, 71, 72...89, 90.

  • Hmm, didn't work. When I restart squid, it tells me start: Job failed to start. On service squid start.

  • You probably need to give different names to each block, like permittedips70, permittedips71

    @polynomial No, it is possible to use same acl name for multiple lines. He should look into squid cache.log for errors.

Although this is a very old thread but since it still shows up on Google when searching for squid ip range I am going to give a new answer that worked for me.

Squid allows you to specify a range of ips in accordance to:

acl permittedips src 1x.x.x.x-2x.x.x.x

So in this case:

acl permittedips src
