Squid Proxy Server Mac Address based filtering

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

first u have to downlaod squid version 2.5 Stable 14 src.rpm then use command rpm -ivh and install
1. Download ftp://ftp.redhat.com/pub/redhat/linux/enterprise/5Server/en/os/SRPMS/squ

load it with

2. rpm -ivh squid-2.6.STABLE6-5.el5_1.3.src.rpm


3. updatedb

4. vim /usr/src/redhat/SPECS/squid.spec

5. add two line as below at %configure section see last two lines.

%configure \
–exec_prefix=/usr \
–bindir=%{_sbindir} \
–libexecdir=%{_libdir}/squid \
–localstatedir=/var \
–datadir=%{_datadir} \
–sysconfdir=/etc/squid \

–enable-arp-acl \ <==========added line 2

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

8. Then edit /etc/squid/squid.conf

#—-the sample code—–
acl our_networks src
acl aclmac arp 00:08:A1:95:71:D4
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.

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.

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
what is acl rule in squid file in linux


7 vikas kashikar June 18, 2008 at 6:32 am

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.

21 Adnan October 8, 2010 at 6:46 am

I have installed RHEL5 server. I am using squid as proxy server.
I want to block the mac address of some computer that is causing problem in the network.

I have used this acl:

acl blockmac arp 00:A7:88:BA:19:OF
http_access deny blockmac.

When i reload the squid service. It gives an error.
aclParseAclLine: Invalid ACL type ‘arp’
FATAL: Bungled squid.conf line 613: acl macaddress arp 00:A7:88:BA:19:OF
Squid Cache (Version 2.6.STABLE21): Terminated abnormally.

I have read the different solutions. like
but i am not able to do this. i have installed rpm verison of squid.
Can any body help me how to reslolve this issue


22 rootlurker December 7, 2010 at 4:30 am

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



23 Rizwan Admani October 10, 2010 at 12:05 am

Dear ,
you can do it from firewall option
only this mac_address drop port 80 only simple.

how could i solve this?


26 lutfi May 8, 2011 at 4:19 am

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?


27 Hussain May 28, 2011 at 11:45 am

which is the good tool to get all Squid reports according each user’s.


28 jalal hajigholamali June 27, 2011 at 5:23 pm

Very useful and good material…thanks a lot


29 Ali Zaheer November 5, 2011 at 8:07 pm

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.


30 Agung D Fire fist November 21, 2011 at 7:03 am

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
