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.
