Remember, you need to configure DNS on the ScreenOS device before the address book items can resolve the DNS to an IP address.
In this example, we assume the hostname is SSG5, the domain name is abc.com, the primary DNS is 18.104.22.168, and the secondary DNS is 22.214.171.124
Click Network > DNS
Host Name: SSG5
Domain Name: abc.com
Primary DNS Server: 126.96.36.199
Secondary DNS Server: 188.8.131.52
Click Objects > Addresses > List
Address Name: www.facebook.com
Click domain name, and enter www.facebook.com
Click Objects > Addresses > Group
Group Name: Facebook
Move www.facebook.com from Available Members to Group Members by clicking the << button
Select From Trust to Untrust, then click New
Source Address: Click Address Book, and select ANY
Destination Address: Click Address Book, and select facebook
hope this helps you
You don't need a translation going from a lower security level to a higher one. You will also need a nat line for the dmz so that pc's on the dmz will be translated outbound. The only connection that will work on the dmz is the webserver when he's sending traffic outbound with a source port of 80. Something like:
nat (DMZ) 101 10.10.0.0 255.255.255.0
Other than that, it looks like it should be working. You've got permission, a route, and a translation. Maybe "clear local-host 10.10.0.2" to get rid of any bad xlates and try again. Check debg level syslogs, run packet captures, "clear asp drop" then "show asp drop" after an attempt?
From the main configuration screen select Network Setup, and then click on the Connections Tab. In the tabline below that click on Aliases.
At this point you input the Alias IP address and the netmask and add it, selecting port 25. The firewall now knows that it is to forward all traffic on port 25 to the computer that has the IP address you put in.
You should be aware that doing the above opens a direct access point into your network! Port 25 is the port used for SMTP (Sendmail) and it is the most vulnerable and most hacked service on the Internet! You should seriously consider not doing this.
A better option would be to goto the DMZ tab and configure a DMZ net on your firewall - you will need to obtain a second routable IP address from your ISP to do this though. By creating the DMZ and then routing port 25 to a machine inside the DMZ you isolate the machine running SMTP from all of the other machines inside your protected network and so make a compromise much less likely.
All of the systems inside your protected network will still have demand access to the machine in our DMZ, but the machine in your DMZ would be unable to initialize access to the protected network, which is a much safer setup.

Is Virtual Router Redundancy Protocol
(VRRP) supported on Juniper firewalls? (KB ID: KB10892)
This is probably what is going on with
your setup but without more information I could not be 100% sure.
Established sessions need to
re-establish when the VPN Redundant Gateway fail-over occurs (KB ID:
If you're within a network and try connecting to computers on it with the WAN public IP, it simply won't work - you must use the network IP.
On an external Internet connection, it should connect fine to the public IP. If you have access to an external machine (remote desktop), or if you know of an FTP proxy, you can try it that way.
I also believe http://www.webftp.co.uk/ a web based FTP client would act as somewhat of a proxy, you could try that with the public IP and see how you go.
The Netgear FVS124-G is a superb combo VPN firewall DSL/Cable small business router. Loads of features and Dual Wan to boot. I highly recommend it's use in small businesses
Keeping the necessary firewall, you are missing another component in a properly segmented network, a VLAN switch. It is highly customizable and gives you the configurability and speed you are asking for.
Look at it's features here:
The normal network security plan is:
Internet -->Firewall-->Router (or Firewall/Router)-->VLan Switch-->Individual computers or VLan subnets.
Using these two components together makes a more configurable and MUCH easier to setup network than using, say, one Sonicwall, or one CISCO PIX-501-BUN-K9 (which doesn't do VLan and you have to know Pix commands)
