+<strong><h1>NAT VLC:</h1></strong>
+<p><strong><h2>Explanation:</h2></strong><br>
+ Set up a computer so that it forwards all packets meant for a certain address, to another computer.</p>
+<p><strong><h2>Instructions:</h2></strong>
+ <h3>1. Create two VMs. SimpleArbiter using the disk simpleArbiter and NATServer. </h3>
+ You can get the disks at polz.si/media/uploads/kpov/virtualke. As for the NATServer VM, you can use any disk you want like base-student-desktop-2014.
+<br>
+ <h3>2. NATServer should have two network interfaces, one should connect to the simpleArbiter VM and the other to the internet.</h3>
+ Adapter 1 should be NAT and adapter 2 should be Internal Network.<br>
+ Simple Arbiter must be connected to the Internal Network.
+<br>

+ <h3>3.On NATServer use ifconfig or /etc/network/interfaces to configure the network interfaces you created in virtualbox.<br></h3>
+
+ -vim /etc/network/interfaces<br>
+ -Set it up like this:<br>
+ auto eth1<br>
+ iface eth1 inet static<br>
+ NETMASK 255.255.0.0 # Specify based on your requirement<br>
+ IPADDR 192.168.2.1 # Gateway of the LAN<br>
+ NETWORK 192.168.0.0 # Optional<br>
+ ADDRESS 192.168.0.0 <br>
+ -ifdown eth1<br>
+ -ifup eth1
+<br>
+<img style="width: 500px; height: 310px;" src="../images/2.jpg" alt="slika-2"></img>
+ <h3>4. Configure SimpleArbiter so that it uses NATServer as the default gateway.</h3>
+
+ <h3> 5. Set up DNS (etc/resolv.conf) on NATServer.</h3>
+ vim /etc/resolv.conf
+ nameserver 203.145.184.13 # Primary DNS Server provided by the ISP<br>
+ nameserver 202.56.250.5 # Secondary DNS Server provided by the ISP<br>
+ Than we set up the host:<br>
+ vim /etc/hosts<br>
+ Replace the first line with:<br>
+ 127.0.0.1 nat localhost.localdomain localhost<br>
+
+ <h3>6. Enable IP forwarding on NATServerju (should be run as root).</h3>
+ echo 1 > /proc/sys/net/ipv4/ip_forward
+
+ <h3>7. Set up NAT on NATServer using iptables.</h3>
+
+ apt-get install iptables<br>
+ iptables -F<br>
+ ptables -t nat -F<br>
+ iptables -t mangle -F <br>
+ iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE<br>
+ iptables -A FORWARD -i eth1 -j ACCEPT<br><br>
+
+ service iptables restart
+
+ <h3>8. Use vlc on simpleArbiter to watch the video over your network. </h3> <br>
+
