NTI PIX Comparison
This is a comparison of the Network Safety NetNAT product
with the Personal Internet Exchange of Network Translation Inc. All
information on the PIX was obtained from the NTI web pages.
Conservation of Internet Address
NTI will allow you to connect "over 1000 hosts...via a single Class C."
The NetNAT will allow you to do the same with a single IP Address.
If
you're an Internet Service Provider, you may use our NetNATs to connect
over a quarter million hosts via the same Class C that NTI would use
for a single site.If you build large private Intranets, you can
use a single network model for each site or business unit, even using
exactly the same network addresses at each site, and let them communicate
with each other and with the Internet through our NetNATs. You may
wind up with just one IP Address visible to the Internet! Even
if you have a handful of addresses this
will greatly simplify your public DNS administration job!
Internal Gateway Hosts
NTI permits you to enable access to particular hosts on the inside of
your network so that they may be used as email gateways or other
services. With their method, that costs you an external IP Address.
With our NetNAT's Server Port Mapping feature, we can map inbound
requests to email or other gateways without setting aside a dedicated IP
Address. In fact, you may have dozens of inbound services
distributed across dozens of internal servers, and still share a
single IP Address with your internal clients!
Fixed Mapping of IP Addresses
Sometimes you really need fixed mapping of internal "actual" IP Addresses
to external "apparent" IP Addresses. We provide this simple function
just like NTI does.
Dynamic Mapping of IP Addresses
NTI assigns apparent IP Addresses to internal clients on an as-needed
basis, but maintains a one-to-one mapping between internal and
external IP Addresses. We reuse the external IP Address and re-map
the external port number. We provide individualized support for the
few client/server protocols that are sensitive to port number, to
permit transparent use of these by your users.
The NTI pricing is based on the number of simultaneous users you
expect, with prices reaching to beyond $20,000 in some cases. We
don't consider making you use more external IP Addresses a feature
that you should pay for. Actually, we see that as a lack of imagination.
So, why should you pay more for it?
NTI's base price for a 32-IP Address unit is $8995. Their prices
can reach $300,000 when more addresses are needed. Ours for a
2-ethernet unit without the address limit is $2995.
We have lots of other models, with different interfaces and WAN capability.
If you build the
unit yourself, we'll sell you the software for $1000 (US and Canada only,
International pricing is available on request). Check
the build it yourself page for hardware
requirements. Contact us if you wish
to resell our products. We have a much better reseller program than
you will find on the PIX.
NetNAT Unique Standard Features
Multiple Private Networks
If you have two networks that need to communicate, but that also
need to be concealed from each other, the NetNAT may be told that
each is "private" so that no network topology or addressing information
is exchanged. In this case, all inter-network communication uses
translated addresses.
If you have two private networks and a public one, a 3-ethernet NetNAT
may be used to interconnect them, possibly eliminating an expensive
multi-LAN router. The two private networks may be hidden from each
other or not, as you wish.
Logging of Deflected
and Permitted Accesses
If desired, the NetNAT will log via syslog any attempted access from
the outside that is denied by its firewall features. You will see
the attempts that fail, as well as those that you permit, plus the
bandwidth used for the authorized services. If you're providing Web
services for hire, this gives you the numbers you need for billing.
Internet Access Control
This upcoming NetNAT feature allows your internal hosts to be placed
into groups by function, and then given default access rights for
appropriate services. When you wish to permit more access, you may do
so from your Web browser through the NetNAT's builtin Web server. This
gives you control over when the Web may be explored, and by whom. When
you give them enhanced access rights, you also specify a timeout, after
which the access reverts to the group's default rights. This is perfect
for the school or small company.
Integral Frame Relay Support
With our optional RFC 1490 Frame Relay Adaptor, your NetNAT can be your
complete solution to Internet connection, address translation, security
and access control. We're compatible with most makers of routers,
including Cisco and Wellfleet.
Demand Dial PPP
For the truly small site, our smaller DialNAT gives you all of these
functions with dial-on-demand connectivity via PPP. The link establishes
itself when any of your users try for an offsite service, and stays up
as long as accesses continue. Your Internet Service Provider sees your
DialNAT and its IP Address, and has no idea that all of your users are
sharing the link.
Online Documentation
All NetNAT and DialNAT documentation is online on the device's builtin
Web server. In addition, the configuration file is just another Web
page for you to view.
