Special Forums IP Networking [SOLVED] AFWall+ iptables help Post 302890544 by Corona688 on Thursday 27th of February 2014 11:16:33 AM

This is what I use on our routers, which are oldish PC's running Linux, to block a particular customer's MAC from our WAN:

Code:
# Block local traffic
iptables -A INPUT -m mac --mac-source 00:00:00:00:00:00 -j DROP
# Block routed traffic
iptables -A FORWARD -m mac --mac-source 00:00:00:00:00:00 -j DROP

Your current firewall configuration may be relevant. If there's a -j ACCEPT rule which matches before these rules, these will be skipped. IOW, these rules should come early.

It requires NETFILTER_XT_MATCH_MAC to be selected in your kernel. If it's compiled as a module, it must be loaded. It seems to fail silently otherwise, for some reason, which is weird since most other failures like this scream bloody murder.

Phones being rooted shouldn't make a difference since what you're configuring is your router, yes?

NAME
arno-iptables-firewall - Single- & multi-homed firewall script with DSL/ADSL support. SYNOPSIS
/etc/init.d/arno-iptables-firewall [start|stop|status|force-reload|restart] DESCRIPTION
arno-iptables-firewall is an iptables configuration script with support for both IPv4 & IPv6. While it is extremely easy to use one can nevertheless use it in quite complicated environments. All available options are explained in the extensively documented configuration file. The external interface of the system needs to be set up properly in the firewalls configuration file (EXT_IF). The default behavior of the firewall is to deny all incoming connections. For additional requirements not covered by the configuration file custom iptables rules can be placed in /etc/arno-iptables-firewall/cus- tom-rules. This file is automatically parsed by the service script. See the README file (eg. in /usr/(local/)share/doc/arno-iptables-firewall) for an example how to manage logging of firewall events through syslogd. The arno-fwfilter script can be used to make the firewall logs more readable for humans (see manpage). Several plugins for the firewall script are available online. Plugins can be downloaded from http://rocky.eld.leidenuniv.nl/ Please see the README file for more information. FILES
