Multiple devices with a public IP address on a Juniper SSG-140 firewall
Posted on 2011-03-22
I have a network which is designed for Video Conferencing. At this moment I have a Cisco VCS Expressway, a Cisco VCS Control, a Codian MCU and a Tandberg Management Suite running outside my firewall, connected to a Cisco Catalyst 2950 switch.
Everyone from the outside should be able to connect to these devices using at least SIP and H.323 and these devices need to be able to connect to the Internet.
Now we want to secure this, by putting all these devices behind our Juniper SSG-140 in a DMZ. Each of these devices has a public IP address, which should not change because then we have to update hundreds of video devices, which is not an option.
Our public IP addresses range from x.y.z.97 - x.y.z.125. Our ISP gateway is x.y.z.126 and the Primary DNS Server is x.y.z.70 (different Host ID than the other addresses).
I'm personally not really experienced with Juniper products, could someone guide me with this?
