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 -
- slika-2

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.

Naloga na hitro:

- Nastavi računalnik tako, da bo vse pakete za določene naslove prepošiljal na drug računalnik, vzpostavi NAT.

Navodila:

1. Postavi dva navidezna računalnika. SimpleArbiter z diskom simpleArbiter ter NATServer.

- Virtualke dobiš na (polz.si/media/uploads/kpov/virtualke). Za NATServer lahko uporabiš base-student-desktop-2014. -
-

2. Postavi NAT server tako, da ima dva omrežna vmesnika. Z enim naj bo povezan na simpleArbiter, z drugim pa na internet.

- (settings-Network) Adapter 1 nastavimo na NAT (omrežje), adapter 2 pa na InternalNetwork (lokalno).
- Simple Arbiter nastavimo na InternalNetwork(lokalno). -
- slika-1

3.Na NATServer z ukazom ifconfig in z datoteko /etc/network/interfaces skonfiguriraj omrežne vmesnike
- tako, da bo en povezan v WAN (internet) in en vmesnik na LAN (simpleArbiter).

- - -vim /etc/network/interfaces
- -dopišemo:
- 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 -
- slika-2

4. SimpleArbiter skofiguriraj tako, da bo privzeti prehod uporabljal NATServer.

- Nastavi gateway, da ima IP od NATServerja.
- route add -net IP netmask MASK default gw IP dev eth0
- -

5. Nastavi DNS (etc/resolv.conf) na NATServerju.

- 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
- Nato nastavimo še host:
- vim /etc/hosts
- Prvo vrstico zamenjamo z:
- 127.0.0.1 nat localhost.localdomain localhost
- -

6. Omogoči posredovanje IP naslovov na NATServerju.
