First off, please forgive my lack of knowledge as we used to have a Network Admin that handled all this however he has since left the company and hasn't been replaced yet... so sadly it falls on me. As far as my knowledge level goes, I can handle the basics including policies and such, however I am struggling hard to wrap my head around why this isn't working.
We have a Juniper SSG-140 firewall device that has a number of Interface ports configured:
All addresses prefix with "192.168.":
0/0 - Trust
0/1 - DMZ
0/3 - Shared DMZ
0/6 - VOIP\VOICE
0/7 - ***NEW INTERFACE***
0/9 - Untrust\Internet
Basically what I am wanting to do is create a new VLAN on our 192.168 network for Interfact 0/7 which will provide a gateway address of 192.168.55.254 (all other addresses are in the 192.168.x.x range). I have created the interface port as the attached screenshot and gone to what will be the new domain controller and setup a static IP on it as 192.168.55.200 with 55.254 as the gateway and I cannot get any conenctions externally. I have tried pinging Google's 8.8.8.8 IP but get no reply. I also setup 2 policies to allow HTTP, HTTPS and PING between the new zone and the untrust as well, being unsure if that was how it "routed" or knows it's ok to let the traffic out.
Thanks much for any help!!!
