Nearly like a router, but works at level 2 and greatly lowers the traffic
any one station on the network sees. It also improves network utilization
by reducing collisions.

Bad analogy (IMnsHO at least) -- hubs can connect to other hubs, but
access points cannot connect to other access points.

Bridges can actually bridge between two different networks.

Switching is not routing. A switch differs from a hub in that traffic
is directed to the single destination, instead of being broadcast to all
destinations.

True - I was trying to be simplistic rather than nit pick details.
Although, access points with WDS can connect to each other...

You say it directs traffic I say it routes traffic. The two verbs can
mean very closely the same thing. The actual switch hardware does in a
way "route" traffic by sending the packets to their proper destination
in much then same way a router "directs" traffic to its proper
destination. It is just done at a different abstraction layer. Both
devices send traffic to a specific place as opposed to a hub that sends
all traffic everywhere.

Anyway, I'm not much for arguing over little details. The original
poster looked like he just wanted a simple explanation so that's what I
gave.

That's not a nit pick -- that's a fundamental difference.

But not as clients.

Not in technical terms -- they are fundamentally different, and a misuse
of the terms.

No offense intended, but inaccurate information can do more harm than
good.

As the saying goes.......'it's all in the details.'

The typical LinkSys/D-Link/Netgear Cable/DSL router is not really a
router either. It is a NAT device.

It's main function is not to 'route' packets anywhere, it is to translate
packets from one or more private IP addresses on a LAN to make the
destination look like the internet (or WAN) IP of the NAT-Device itself,
so other hosts on the internet can get data back to the PC with the
private IP.

Even though it's also a NAT/PAT device, it _is_ still a router
nonetheless.

It is, but in the broadest sense of the word.

But when I'm used to working on Cisco and Cabletron/Enterasys
Routers......

I guess there's a question I've never had answered, that might make it
seems to be more of a router. Possibly you can answer it......

You have:

Internet <--> a NAT router <--> PC <--> LAN of PC's.

Rtr = 192.168.1.1

So above, the PC has 2 NICs, and set to route packets.
Rtr side = 192.168.1.2
LAN of PC's side = 192.168.100.2

The LAN of PC's each have a 192.168.100.x IP with a gateway set of
192.168.100.2.

So an internet bound packet from .100.10 will be sent to the PC as it's
gateway. The PC's gateway is the rtr, so the packet will be sent to the
rtr.

What will the router do with it ? It's source is from a different subnet
than the router eth is. Will it NAT this packet and send it out on the
internet ?

The rtr firmware also needs to offer a place to enter static routes also,
to be able to get back to the .100.x network thru the PC. Not all do.
Mine does not, I know some older Linksys rtr's could hold static routes
like that. There are others I'm sure.

Regards,

DanS

It is, in the true sense of the word (router). RFC 1009:

Router A router is a switch that receives data transmission
units from input interfaces and, depending on the
addresses in those units, routes them to the
appropriate output interfaces. ...

For example, given a local network 192.168.0.0/16, and a packet
addressed to 66.102.7.104, a low-end consumer router knows to "route"
that packet to its WAN port, sending it to the gateway on that port.
Simple, yes, but routing nonetheless.

Difference of degree, not kind.

Why have a PC between the NAT router and the LAN of PC's?

ICS (Double NAT)? Real routing? Or bridging?
I'm going to assume ICS (Double NAT).

Route it.

Depending on how the PC is configured, it's probably coming from the PC.
Double NAT.

Yes.

No, it sends it back to PC as the origination point.

No static route is needed.

But the router is not connected to the 100.x network, so it doesn't have
a way back, I would think it needs a static route pointing to the PC.

Depends on what the PC is doing, which is still a secret.

No, not a secret, I already said it had IPRouting enabled.....

What you actually said was "set to route packets", which is pretty vague
since it could have meant any of a number of different things, including
ICS. You ducked my questions, leaving it a secret.

I think you'll find this more helpful with regard to how packets get
back through the Windows router:
<http://www.petri.co.il/configuring_routing_in_w2k_pro_xp_pro.htm>

In other words, you would need to configure the Windows router as a
gateway in the hardware router.

Yes, that is what I said, you would need to add a route in the router,
pointed at the PC as a gateway, so it knows how to get to the subnet on the
other side of the PC.

So the question was, will the simple home cable router accept a packet that
was forwarded to it, with a different source IP subnet than the routers own
ethernet ?

I have never had to do this myself, which is why the question was posed.

Not a static route, a gateway. That's a subtle but important
difference.

Sorry, but I choose not to play, since the idea is speculative and
silly. Either switch the Windows router to ICS, or take it out of the
network path.

Why is this idea 'speculative and silly' ?

You can not see anyone breaking up their network into 2 segments like this?

If so, why would there be articles on how to do it, such as the link I
posted and the link you posted.

My posed question is valid. The only reason it is speculative about it is
you and I don't know if it will work or not, as neither of us have tried
it.....and, far from silly.

(Silly is like the post from a week or few ago where the poster was
creating a network by connecting each 'slave' PC into a separate NIC on a
master PC that was doing ICS, from 4 NICs, out 1 other NIC to the internet.
Now THAT is silly.)

(Oops, that was a different group....

Because it makes no real sense.

Not if they know what they're doing.

I suppose there can be valid cases for using a Windows machine as a
bridge, but this isn't one of them, and I'm frankly hard-pressed to
think of a case where different topology or just a real dedicated
hardware bridge wouldn't make more sense. That Microsoft has bridging
support and an article on how to do it isn't any sort of real
endorsement.

>My posed question is valid. The only reason it is speculative about it is


You've yet to post a valid reason for that configuration.

>you and I don't know if it will work or not, as neither of us have tried
>it.....and, far from silly.


I actually do know, and even gave you the answer.

Not bridging, routing.

Why ? There is no valid reason for dumping a Chevy BB 454 into a street
vehicle that never touches a drag strip, but it's done constantly.

No, you never said, 'Yes, a typical home router will accept those
packets', or 'No, a typical home router will not accept those packets.'

Maybe what you claim as an answer was this..... 'Either switch the
Windows router to ICS, or take it out of the network path.'...but that
does not answer the question.

Microsoft calls it "IP Forwarding".

I have no idea why you haven't.

Not by me. Nor am I interested in the technical issues.

I did.

I'm done. Have the last word.
