{{howto_header}}

The goal of this tutorial is to create a mobile router and firewall. The wireless connection will connect to a network and then provide a route to an internal network of machines that, themselves, do not have wireless connectivity.

= OS Install =

I perform a normal [[Fedora]] 18 install. Once the OS is installed, I disabled [[selinux]] and [[firewalld]].

<syntaxhighlight lang="bash">
setenforce 0
sed -i 's/SELINUX=.*/SELINUX=disabled/' /etc/selinux/config
systemctl disable firewalld.service
</syntaxhighlight>

I don't want the graphical interface to run on boot as this will be, essentially, an appliance. This tells the system to boot into command-line mode only (sort of like init 3 on pre-[[systemd]] linux machines).

<syntaxhighlight lang="bash">
rm -f /etc/systemd/system/default.target
ln -s /lib/systemd/system/multi-user.target /etc/systemd/system/default.target
</syntaxhighlight>

Next, I do an OS update and reboot.

<syntaxhighlight lang="bash">
yum -y update && reboot
</syntaxhighlight>

= Configuring the Network =

In my case, I want the wlan0 interface to be the default gateway. I will have two wired connections; p6p1 will face the network I want to provide [[dhcp]] services on and provide an internet connection for. The eth0 interface is totally optional. In my case, this is a slow USB ethernet device used to provide access to a dedicated management network. No dhcp services will be provided on this connection.
