If by group you mean some network topology grouping. The network admin
should have some CIDR range that describes each group. That can be
implemented in Squid ACLs for a simpler and faster config.
For example something like this filtering grouped by network, then some
individual IPs with a blocklist applied;
acl networkA src 10.2.0.0/16
acl networkB src 10.15.0.0/16
acl ipsA1 src "file_with_A1_group_IPs"
acl ipsA2 src "file_with_A2_group_IPs"
acl blockA1domains dstdomain "file_with_A_group_blocklist"
http_access deny networkA ipsA1 blockA1domains
http_access deny networkA ipsA2
http_access allow networkB
Hello,
We have ip groups with individual ips. We can't group by networks. For
example:
Group Filter IT 10.30.1.2,10.30.1.8,10.30.1.28,10.40.2.56, 10.50.5.5,
etc, etc. (5000 ip addresses more or less).
Group Filter Press 10.30.1.29,10.40.2.22,10.60.1.200, etc (10000 ip
addresses, aproximately).
.
.
.
Keep in mind that these groups are constantly changing.
Each group has permission to access one or more categories blacklists.
In this scenario, what is the ideal solution for best performance?:
- A file with lists ips in squid?.
- A file with lists ips in squidguard?.
- A query to mysql database for external acl in squid or squidguard?.
- A query to ldap for external acl in squid or squidguard?. (We have ip
addresses for user saved in ldap server).
Greetings.
