System Setups

VyOS Setup

Steps

1. Build <attacker><targets> VMs

2. Finish general setup for <firewall> VM

3. Configure IP address to the firewall and enable SSH

   #config
   #set interfaces ethernet eth0 addresss x.x.x.x/xx
   #set service ssh
   #commit
   #save
   

4. Log in to the FW from other VM

   (I logged in from Kali for convenience)

   # ssh [email protected]/xx (IP address configured in step 3)
   

5. Configure FW
