Initial Setup

Firewall

I used sections of https://github.com/echadbourne/sec-350/blob/main/fw-configs/assessmentprep/fw01.txt as a reference

Start with the firewall, edge02. I had to add a network interface, connect all of those interfaces to the right network, then go into the box and configure the default password, hostname, and the addresses and descriptions of the network adapters.

Next is the default route to the internet via the default gateway of 10.0.17.2

• set protocols static route 0.0.0.0/0 next-hop 10.0.17.2
• set system name-server '10.0.17.2'

Then the nat rules, specifically those for the DMZ to the WAN

• set nat source rule 10 description 'NAT FROM DMZ to WAN'
• set nat source rule 10 outbound-interface 'eth0'
• set nat source rule 10 source address '172.16.50.0/29'
• set nat source rule 10 translation address 'masquerade'
