The Direcway 6000 unit had a firewall as part of the built in hardware function. You used

to be able to modify the firewall by going to :

http://192.168.0.1/fs/dynaform/firewallconfig.html

We had recommended users make use of this firewall in their residential networks. It

blocked port attacks but did not block storms or performed statefull packet inspections.

As it turns out the screens had been there but the underlying functionality was never

completed. A recent DW6000 software upgrade has removed this function from user

modification all together.

It is unknown but it appears that with the DW7000 some attempts may be made to fulfill

the firewall capabilities of this NTI.

For the consumer version we today disable the software firewall on the workstation. For

the Professional Version a hardware firewall should be placed between the DWx000 and

the LAN on the users intranet. The problem is that for a hardware firewall to function it

generally must control the DHCP and NAT functions to perform the statefull packet

inspections and protect the underlying network. The residential service plan for a

DWx000 does not allow the user to modify the base function of the DWx000 to turn off

DHCP and NAT. A user must subscribe to the Professional Direcway service to get a

static IP address causing the DWx000 to be configured with NAT off. Once this is done

then the DWx000 functions like a “cable modem” or “DSL modem” network termination

interface and allows the consumer to purchase a separate router with the firewall, DHCP,

and NAT function built in.

NOTE: Hughes has signed an agreement with McAfee software for their firewall and

virus protection. We still maintain that a software firewall is worthless, especially since

there may be multiple computers on the LAN and each one would have to have firewalls

installed and maintained. We realize that firewalls are of limited security viability and are

only a single step in an overall security plan. If viruses plague you that much then maybe

you should investigate a migration from Windows or Microsoft versioned software to a

UNIX variant such as the Macintosh.
