Netscreen 5GT - Transparent Mode w/ Cisco 1841 question

Posted on 2006-11-23

Hi all,
New to Juniper products, and wanting to find out if the following setup will work:

[Public Server]'---(Trust Port)[Netscreen 5GT Transparent Mode](Untrust Port)---[Cisco 1841]---Dedicated Link
[Public Server]'
[Public Server]'
`[Private Network]

ISP has provided /28 block of IPs, all Public Servers and Router will have a public IP address.
Cisco 1841 ethernet interface connected to the Untrust port, Trust Ports connected to public servers.

Is all that i have to configure on the router and Public Servers, is a static IP and gateway pointing to the eth interface of Cisco?
Will the Public IP passthrough the Netscreen?

Edit: Also, would i be able to block ports on the Netscreen, using Trust and Untrust policies?

Yeah that would work.

1. Put all the servers and eth1 interface of cisco router in the same subnet block.

2. Put the 5gt in transparent mode and also create assign an ip address to the vlan1 interface of 5gt so that you can manage that.

3. You could block ports on the netscreen if you want in the same using trust and untrust policies (which would be either predefined services or you can create custom services with the ports you want).

Suggest you to run the 5.40r2 code on 5gt.
