How to configure SSG 140 as the edge fire wall
I have purchased Juniper SSG 140 Firewall + VPN appliance. Currently I am using ISA as the edge fire wall. Now I want use SSG 140 as the edge. I have to NAT (one -one) 4 Servers to SSG. I have 4 public IPS with me. I am totally new to SSG 140.
I need to know the step by step procedures to configure the en/0, en0/1 and en0/3 (trust, Untrust and DMZ). I
To which Interface I have to use MIP and how for the servers which I have to NAT. (the private Ip range for the NAT serves is 192.168.30.0/24).
How should be the policies to allow traffic for the NAT servers.
I prefer to use the WEBUI for the SSG not CLI.

Well I had look at it before posting my question. A couple of doubts
The interface en0/2 is used for untrust (out side) i.e. I have to assign one of the Public IP I have.
The MIP has to be done on the untrust ie public ip - private IP - net mask of the public IP. I am getting confused over here. When I try to MIP one of my Public IP ( I have 4 IPS- mask 255.255.255.240) I get an error that "one ip range is used by (sub) interface Ethernet 0/2".
I have to use the 3 Public IP for different servers by MIP. Can you shed some light on it.

I'm not sure how you're doing it, can you post the config what you have as of now and then I'll see if there is anything that needs to be modified.

These are just the config which I did when I started with the SSG (rapid Deployment wizard). Kindly not that I am only a beginner and I am very much used to ISA only.
What I want to achieve is this.
Untrust- has to be configured for outside access (internet)
I have to NAT 3 Public IPS to private IPS for ISA (web proxy), Exchange and Black Berry.
I have to connect Symantec SMS8340 to the SSG to use for SMTP.
I do not want to use DMZ rather only one-one NAT for the above 3 servers
Thanks in advance

Rajesh,
Thanks for the tip. I did add that policy as per your advice and I added the services http, https,dns etc for the internet browsing on a server which is connected to the DMZ. This server has 2 net work interfaces. one is configured with a 192.168.2.0/24 (and is joined to my domain) the other inter face is same as the DMZ subnet of SSG, which 192.168.30.0/24.
Now the trouble is that I can not access internet on this server. Am I missing any policy or any other settings?
Zac.

I thought from beginning we're working on trust/untrust pair and you didn't want the DMZ zone???
I don't know the limit of MIP, but you can for sure configure what you have.

Can you tell me what is not working now? I need to know the problem to offer any help. Looks like you've configured the MIP and policies.
