I have a Netscreen 5GT adsl which constantly drops the adsl connection. My ISP cannot see this
and reports the connection as having been up for days even when you can see from the 5GT logs that
that it is being dropped every few minutes.
I want to replace the onbaord adsl modem with another external one to see if the problem goes away but am not sure if it is possible to configure one of the ports as untrusted to allow the firewall to function.
