How do i setup a static route on a Netscreen 5xt?

I have a Netscreen 5xt which im using as an internet gateway. I have a connection to another network which is provided through a cisco 2620.

The trust network is 10.1.1.0/24, the network provided by the cisco is 10.60.0.0/16
The netscreen gateway IP is 10.1.1.1 and the cisco gateway is 10.1.1.253

I want to add a route onto the netscreen so i can access the 10.60.x.x network via the cisco.
I used this command: set route 10.60.0.0/16 gateway 10.1.1.253

I cant ping the network though. Ive tried using the webui too.

you don't have to add any route, there supposed to be a default route on the Netscreen for all subnets other than the internal 10.1.1.0/24, but what is stopping you maybe is perhaps echo-replies coming back from the Router are being dropped by the Netscreen, youd need to enable a rule on the outside interface of the netscreen to permit echo-reply from outside interface

The netscreen is used as an internet gatway, so the untrusted (or outside) interface is connected to the internet via a modem. The cisco router is connected to the inside trusted network.

thanks for clarifying, in that case you'd need to add this subnet to your trusted network in case you want to reach it

Well, you actually got a smallish challenge here.

Since both the Cisco router and your Netscreen device are in the same network (10.1.1.0/24), you have two exits from that network, and traffic leaving your LAN for the 10.60.0.0/16 won't actually pass through the Netscreen. The Netscreen won't route traffic back out on the same interface it receives traffic, nor will it send ICMP redirects.

Your clients will only have one default gateway, so they'll send all the traffic to the Netscreen, which will drop it.

The best solution would be to upgrade your netscreen to a device with another interface (typically a DMZ interface) where you could connect your router, so the traffic would actually pass through the Netscreen and behave like normal. If this isn't an option (it isn't free, you know), you're left with two "config only" options (free!):

1). Define static routes on hosts needing to reach the 10.60.0.0/16. Massive management overhead if there are many hosts. Can be solved with login scripts etc, but messy.

2). Switch IP on Cisco router and Netscreen. Where the Netscreen refuses to send ICMP redirects, the Cisco will do just that. So, if the Cisco is the gateway where all traffic is sent, it'll forward traffic to the 10.60.0.0/16 as intended, and it'll send an ICMP redirect to any hosts trying to reach the internet, so they'll know where to send traffic destined for the internet. It's not perfect, you'll get a small traffic increase with the ICMP redirects, but it's the best you can get without having to either replace the firewall or configure every single host.

So, summed up, you either need routes on each host, or a default gateway that supports ICMP redirects, which your current default gateway doesn't.
