Explanation:

+ Set up a computer so that it forwards all packets meant for a certain address, to another computer.

Instructions:

1. Create two VMs. SimpleArbiter using the disk simpleArbiter and NATServer.

+ 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. +
+

2. NATServer should have two network interfaces. One should connect to the simpleArbiter VM and the other to the internet.

+ Adapter 1 should be NAt and adapter 2 should be Internal Network.
+ Simple Arbiter must be connected to the Internal Network. +

3.On NATServer use ifconfig or /etc/network/interfaces to configure the network interfaces you created in virtualbox.

+ + -vim /etc/network/interfaces
+ -Set it up like this:
+ auto eth1
+ iface eth1 inet static
+ NETMASK 255.255.0.0 # Specify based on your requirement
+ IPADDR 192.168.2.1 # Gateway of the LAN
+ NETWORK 192.168.0.0 # Optional
+ ADDRESS 192.168.0.0
+ -ifdown eth1
+ -ifup eth1 +

4. Configure SimpleArbiter so that it uses NATServer as the default gateway.

+ +

5. Set up DNS (etc/resolv.conf) on NATServer.

+ vim /etc/resolv.conf + nameserver 203.145.184.13 # Primary DNS Server provided by the ISP
+ nameserver 202.56.250.5 # Secondary DNS Server provided by the ISP
+ Than we set up the host:
+ vim /etc/hosts
+ Replace the first line with:
+ 127.0.0.1 nat localhost.localdomain localhost
+ +

6. Enable IP forwarding on NATServerju (should be run as root).

+ echo 1 > /proc/sys/net/ipv4/ip_forward + +

7. Set up NAT on NATServer using iptables.

+ + apt-get install iptables
+ iptables -F
+ ptables -t nat -F
+ iptables -t mangle -F
+ iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
+ iptables -A FORWARD -i eth1 -j ACCEPT

+ + service iptables restart + +

8. Use vlc on simpleArbiter to watch the video over your network.
