Need Advice on NetScreen 5xP
I'm using a NetScreen 5xP with a WIN2000 Pro Server with cable internet
access. Been having some issues with loss of signal and cable company today
came out and re-strung a new line to the building and a replacement modem.
Could NOT get data flow after the new modem was installed. I could connect
the new modem directly to a laptop and connection was possible. Put that
same modem on the router no connection. I finally would up putting the
'original' modem back on line and had immediate connectivity. The
router/firewall is apparently tied into the the MAC (?) on modem A? How do I
change this?
My config settings are:

There is no way to permanently tell the NS about a specific MAC on the
modem. But if you didn't power cycle the unit it could have still an arp
entry for that IP at the other modem MAC. So when you plug in the new
modem, do a "get arp" at the command line an you'll see the entry, if it's
not the right MAC do a "clear arp" and it will relearn it with the new one
as soon as data tries to flow. Since you appear to have a static untrusted
IP config, the bad arp entry could cause your issue whereas if you had PPPoE
that couldn't happen.

If you power cycled it, it won't help to flush arps.
When your PC connects through the modem, observe the network parameters.
Then connect your pc to the old modem and obsever the network parameters.
Now try each on the NS and check out the untrust interface properties for
each. Look for discrepencies between how the pc talks to the new modem and
how the NS talks to the new modem. I suspect a different network or DHCP
setup on the new modem vs a static setup on the NS that works for the old
but not the new. Guessing still given limited info, but that's a start.
