Keywords: A3 setup
NOTE: Some of the IPs on the assignment have changed since the time when these instructions were created. However, the setup steps should be the same, just use the new IP information provided on the assignment webpage.

REMEMBER: vmware "vmnet8" interface corresponds to your private network (192.168.0.*). "vmnet1" corresponds to your public network (10.10.10.*).

goto /virtual/[YOUR_DIR]

Make sure you have the following VMs unzipped: BT3, dsl, FC4, RH7.2, Ubuntu 8.04, WinXP and Windows 7 (check /virtual for windows 7 first).

Note that to switch DSL machine between the private and public networks, you will need to switch its interface (vmnet1 vs vmnet8). OR unzip a second copy.

You can choose "I moved it", when booting up the VMs.

IMPORTANT: When you are done working, properly suspend all of the VMs!

FC4 setup

Log into FC4 (root/password). Check that eth0 is assigned 10.10.10.10. Check that eth1 is assigned 192.168.0.10.




---

Windows XP setup

Login into Windows XP VM (csc347/password). Go to: Start->Control Panel->Network connections.

Open up Local Area Connection. Go to Properties->Select Internet Protocol (TCP/IP) -> Go to Properties.

Assign the following IP configuration: IP address: 192.168.0.33. Subnet mask: 255.255.255.0. Default gateway: 192.168.0.10. Click Ok->Close->Close.

Open up a terminal and ping 192.168.0.10. Make sure you get replies.

DSL setup

First, change the network interface of the DSL VM to "vmnet1".

Changing IP of DSL: Go to DSL(Left,lower corner)->Setup->Net config->Netcardconf. Set ip to (for example) 10.10.10.55. Set default gateway to 10.10.10.10. Open up a terminal and try to ping 10.10.10.10 (ie, your gateware/firewall). Log into FC, try to ping 10.10.10.55.

Remember your DSL will play multiple roles. Some on the private network, others on the public network. To bring DSL into the private network, change its vmware interface to VMNET8. Change its IP and default gateway. (For private network, the IP you should set it to 192.168.0.23 with 192.168.0.10 as the gateway)

Ubuntu 8.04 setup

IMPORTANT: Choose "I moved it" when booting up the VM.

Log into Ubuntu VM (root/743vulnerable@u1m). Ping 192.168.0.10. Make sure you get replies.




---

NOTE: By default, you won't be able to ping the public network (ie 10.10.10.10) from the backtrack. Although not required, you can set its default gateway to 192.168.0.10 (Try: "route add default gw 192.168.0.10 eth0").




---

REMEMBER: After you implement your NAT, change the default gateway on the public machine you are testing to be anything except the correct default gateway. (For example, if I'm testing NAT for 10.10.10.10, I would change its default gateway to 10.10.10.230).
