: Yep, it does. But it is a feature of the router that can be turned off and
: the router will just follow normal Layer3 routing. I could turn our old
: Cisco 2501 into a NAT Device (or NAT Firewall) if I really wanted to.
: However, a NAT Device (like hardware firewalls and those SOHO things)
cannot
: have NAT turned off and cannot fuction as a normal layer3 router.

I don't see a firewall as a NAT device although it may support NAT
functionality. I agree SOHO routers are limited, with the price to match,
but they do perform routing functions.

: A router can double as a NAT Device, but a NAT Device cannot double as a
: router.

I'm not clear on that statement.

Now, don't get ME started no marketing departments. Wish they were in
season.

: What are commonly called
: Cable/DSL Routers should more accuartely be called either "Cable/DSL NAT
: Servers" or possibly "Cable/DSL Firewalls" since their actual function and
: design more closely match that of the common firewalls like Watchgaurd,
PIX,
: etc., although their security and features aren't as robust. I don't see
: people with firewalls like PIX, Checkpoint, or Watchgaurd going around
: calling thier boxes "routers" just because they manage to get a packet
from
: one network to another.

That might also be because their target is to sell firewall functionality.
If a firewall appliance does not route a packet, then it functions as a
bridge, does it not?

: I guess terminology is a little pet-peve of mine. Much of the problems and
: hassles of trying to answer people's questions in these groups is due to
: "butchered" terminology that create a situation where nobody really knows
: what anybody else is really talking about.

My favorite is "domain".

: .......and don't get me started on Cable/DSL "modems" which aren't real
: "modems".... :-)
: There isn't a one of them that "modulates & demodulates" whic is what the
: name means (modulator/demodulator = "mo - dem"). They are just a stupid
: "media converter".

A transceiver?

: Anyway Roland,...I been meaning to ask but haven't seen you around
: lately,....

Sometimes work calls...

: are you planning to go to the MVP Mini-Summit?

I wasn't invited. I'm not an MVP, except on Singapore Airlines. (O;=

: I missed a lot of
: people back in April becuase the crowd was so large. The Security based
: Summint in Nov should be smaller so maybe I can actually find more of the
: folks I'd like to see this time.

Hope so. BTW... Cisco is my switch/router of choice, except for the 700
series, which they bought from someone else and they don't even make good
parking blocks.
