Q. I’m using squid proxy server under CentOS Linux version 5. How to filter a particular MAC address under squid?
A. Not all operating system supports Mac address based filtering. For some operating systems. Squid calls these “ARP ACLs” and they are supported on Linux, Solaris, and BSD variants.
How do I set up ACL’s based on MAC address?
Open squid.conf:
# vi /etc/squid/squid.conf
Local acl, section and append ACL as follows:
acl macf1 arp mac-address
acl macf2 arp 00:11:22:33:44:55
http_access allow macf1
http_access allow macf2
http_access deny all
Save and close the file. Restart squid server:
# /etc/init.d/squid restart

6. rpmbuild -ba /usr/src/redhat/SPECS/squid.spec
7. Wait some time let it compile have cup of coffee :)
then load the rpm
rpm -ivh /usr/src/redhat/RPMS/i386/squid-2.6.STABLE6-5.3.i386.rpm

acl our_networks src 192.168.0.0/24
acl aclmac arp 00:08:A1:95:71:D4
OR
create blockscripts folder in squid folder allow in squid.conf like this
acl aclmac arp '/etc/squid/blockscripts/allowmac.txt
http_access allow aclmac
http_access deny aclmac
http_access allow our_network
#—- end of sample code———
Have a happy arp / MAC restriction with ACL in squid.
Hi
Good Day!!!
I have CentOS 6.6 server installed with Squid proxy 3.5.1 recompiled source RPM with –enable-arp \ & –enable-arp-acl \ options, which are required to enable mac address filtering acl.
I want to allow internet access to only allowed mac addresses via squid. I have tried with below ACL in squid.conf but its not blocking other mac addresses.
acl allow_mac arp 01:23:45:AB:E0:CC
http_access allow allow_mac
http_access deny !allow_mac <======This is to block other mac address
Also let me know if this is possible with iptables.
I need to block internet access to some users but they should able to access samba share on the server.
Please help me to resolve this issue,
Thanks in advance.

Sir,
you have to download source code for squid and recompile with –enable-arp-acl and use that binary for use with mac address.Many vendors like redhat including cebtos do not compile squid with that option enabled. Suse does compile with the said option. Hence you can use suse linux any version and configure squid in that machine if you have one.

web site is block but i want to open web site ony one ip address 192.168.3.1
what is acl rule in squid file in linux
you will have to recompile squid and make it before mac based filtering works.
add –enable-arp-acl to your original configure command in squid and run the following
% ./configure –enable-arp-acl …
% make clean
% make
then the above acls in squid.conf will work.

Hi, its bungled because you put “O” on the mac instead of “0” (zero) .. mac address is only up to “F”.
thanks

you can do it from firewall option
only this mac_address drop port 80 only simple.
hi
how to use the
–enable-arp-acl
to block the mac address
i’ve already use the 3.1 version but it still give an error:
2011/05/08 09:57:24| aclParseAclLine: Invalid ACL type ‘arp’
FATAL: Bungled squid.conf line 33: acl lutfi arp 00:1F:3C:84:14:F3

kovzone# pkg_info | grep squid
squid-3.1.12 HTTP Caching Proxy
how could i solve this?
i’ve found the answer above.. i should’ve do
./configure –enable-arp-acl
before make install
but what if i’ve already install it?
which is the good tool to get all Squid reports according each user’s.
Very useful and good material…thanks a lot
i want to block mac addresses using acl. I have done it this way:
acl badmac arp (mac address)
http_access deny badmac
but i want to block multiple addresses. plz tell me the method how i can create a separate file of blocked mac addresses and create one acl for the same.
you can copy paste your acl rule like this :
acl badmac arp (mac address1)
acl badmac arp (mac address2)
acl badmac arp (mac address3)
acl badmac arp (mac address4)
so on…
http_access deny badmac
