SRX

I searched through other posts but didn't find a definitive solution.
What I am trying to do is add different IP/subnet ranges into my SRX100H. I have a simple, single network setup now that works fine, but when I try to add in another IP range/subnet, it will not work.
For example, I have a network setup with 10.1.1.50/28 setup now that works fine with a few test computers in that range. I have another group of computers with a 172.90.185.60/29 address range and I need them to get setup in this firewall properly, and go out to the internet, but be seperate from the 10.1.1.50 group. Is this possible? If so, how would I add this new group in? Everything I have tried so far hasn't worked.
Before the implementation of this firewall, these two networks were going through a Cisco switch, and then into the ISPs switch with no issue. Both could talk to the internet just fine. The Cisco switch has no special configurations on it or anything. I am trying to place the Juniper SRX100H after this Cisco switch, so it would go ISP switch -> Our Cisco Switch -> Juniper SRX100H -> test computers.

I am including the show config and show interfaces output text files. If you need any other information, I will get it for you. Thanks a ton!

Thanks for those pointer cmia. I am pretty new at this so I am not too familar with either solution. I am getting caught up to speed by reading various articles though.

Can you give me any configuration examples, explanations, or such? 

Thanks

So when you say look at vlan-tagging the external interface, you mean on the Cisco device the Juniper is connected to?

Thanks

Try this, add vlan.1 to the trust zone

 zones {

        security-zone trust {

            host-inbound-traffic {

                system-services {

                    all;

                }

                protocols {

                    all;

                }

            }

            interfaces {

                vlan.0;

                 vlan.1;

Thanks for the recommendation. I am going to try this solution here this afternoon. I will let you know if it works.

That did the trick! Thanks a ton and have a great weekend. I will mark you down for the accepted solution. Take care.
