NEW! Demo the DialNAT!
The Dial NAT Internet Multiplexer
For the Small Office
Designed for the Small Office or Home Office, the Dial NAT has a demand
dial PPP interface, in addition to one or more ethernet
interfaces. We have shipped versions with one or two
ethernets. The one-ethernet version performs pure NAT functions,
while extra ethernets give the administrator the ability to segment
the local IP network without having to buy an expensive multi-ethernet
IP router from another vendor.
The drawing at left illustrates the use of the Dial NAT with one ethernet
interface. The Public interface uses demand dial PPP to connect to
your Internet Service Provider. On that interface, you may have a
fixed, assigned IP Address, or may use a dynamically-assigned address
for the duration of the current call.
The Private interface is on your private Intranet. The devices on your
Intranet use the NAT as their "default gateway" to the outside
world. The topology and computer makeup of your private Intranet
are invisible to all in the Internet.
Public vs Private Interfaces
We call the interface that the Internet can see the "public" interface.
This is the one with a registered address, usually loaned to you by
your Internet Service Provider. We call the interface or interfaces
that attach to your Intranet "private" interfaces. Private
interfaces may use most any IP Network Addresses that you wish,
including those registered to others, although we encourage the use
of those specified in Internet Standard
RFC 1597. No addresses from your "private" network will be
seen by the outside world. If desired, and if you have multiple
private ethernet interfaces on your Dial NAT, your private networks
may "see" each other without restriction. This feature allows you
to subnet your intranet very inexpensively.
Competition Comparison
We know of no competition in the SOHO demand dial PPP NAT/Firewall
market.
