Create DMZ on Juniper Netscreen NS-5Gt
Posted on 2012-09-20
We recently did a circuit cutover at one of our newly acquired sites and inherited a Cisco VPN Concentrator 3000. Before the cutover, the VPN concentrator was connected to the internet router via a linksys workgroup switch which in turn connected to the internet router. The Juniper Netscreen NS-5Gt also connected to this Linksys switch as well as the core router which logically divided the two campuses.
We have since taken out the linksys from the equation and have connected the core router directly to the internet router. The Juniper Netscreen naturally is connected to the internet router as well. So now the VPN concentrator is offline and I am looking to reconfigure starting with creating a DMZ on the netscreen to house the Cisco VPN Concentrator.
Being new to the DMZ world, I am needing a little assistance to get his process going. I currently have three interfaces on my netscreen ns-5gt trust, untrust and dmz (1,3,2). . My question is how to go about setting up the DMZ first since I have never had one in place before. Thanks in advance for the assistance and let me know if you need more info.
