Hi,

Hope there are some Netscreen experts or owners out there who can help
me.

We are considering a Netscreen 5GT Plus as firewall and router for a
small residential network. Basically, we want to share internet access
between 20 appartments with maximum security and reliability at
minimum cost.

I have read in Netscreen's guide Concepts & Examples that we can set
the ports in Combined Mode to have a backup connection to the internet
which is only active if the primary fails (Failover).

This is clever if we have a second line which is paid for based on how
much we use it. It would 'lie dormant' most of the time, costing us
very little.

However, we might also want run another connection all the time for
maximum bandwidth. The two interfaces would then be active
simultaneously, as described under Trust/Untrust/DMZ Mode in the
guide. This is called Load Balancing as opposed to Failover, I gather.

We would like to have the option to use either, but we are hoping that
we don't have to pay extra for the Extended version.

But the guide is not very clear at this point. It says that
Trust/Untrust/DMZ Mode is only available in the Extended version of
the 5GT. But I cannot figure out if this applies to the Load Balancing
function as well as the DMZ, or if that is also available in the
cheaper Plus version.

So I guess the short version of my question is this:
Is Combined Mode with Load Balancing available in the Netscreen 5GT
Plus?

Best,
Mads, Denmark
