Lab / Activity:Assessment – Creating Virtual Network Appliance

Lab Setup – OverviewThe activity was conducted to install and set up a simple firewall using Vyatta virtual machine.

Lab/Activity: Installing VyattaI obtained and installed Vyatta on my local VMware platform. After configuring the platform as directed in the course shell tutorial, I proceeded to configure a basic firewall. Configuring the NAT

I first began to configure NAT for Vyatta

I issued the following commands;configureset nat source rule 1 outbound-interface eth0set nat source rule 1 source address 192.168.56.0/24set nat source rule 1 translate address masqueradecommit

I then verified the appended nat rules by issuing the command;#run show nat source rules

I then proceeded to configure the firewall settings using these commands

set firewall name WAN_IN rule 10 action acceptset firewall name WAN_IN rule 10 destination address 192.168.15.1set firewall name WAN_IN rule 10 destination port 80set firewall name WAN_IN rule 10 protocol tcpset firewall name WAN_IN rule 10 description Allow-Access-To-HTTPset firewall name WAN_IN rule 10 log enable

set firewall name WAN_IN rule 2 action acceptset firewall name WAN_IN rule 2 destination address 192.168.56.0/24set firewall name WAN_IN rule 2 description nat-for-LAN

I also configured additional firewall settings to monitor logs, syn cookies, redirects and source validation.

Summary

Getting appropriate tutorial on this assignment was a little difficult to come by due to changed command configuration. It was however a learning point for me learning the internal commands using the help (?) syntax. I did enjoy it and look forward to developing more proficiency and control over the interface.
