attaching a second router down the line...

[Gordon J. Rattray]

Hi there,

I have my main Linksys router going to the public internet side, gateway
192.168.1.1, and leading from that router internally is another SMC router
with 192.168.2.1 as it's gateway. On my Windows XP machine which is directly
attached to the Linksys router, how can I enable my machine to ping the SMC
192.168.2.1 router?

Thanks,

Gordon

Turn off the routing functions of the second router - make it a switch only.

You can do this:

Internet
|
Public IP
ROUTER 1
192.168.1.1
|
192.168.1.2
ROUTER 2
192.168.2.1
|
COMPUTER : 192.168.2.2
255.255.255.0
192.168.2.1

You should be able to ping anything in the path.

You can NOT do this:

Internet
|
Public IP
ROUTER 1
192.168.1.1
|
COMPUTER : 192.168.1.2
255.255.255.0
192.168.1.1
|
192.168.2.1 (LAN Side Connected to your network)
ROUTER 2
Because router 2 is on a different subnet. Even if you connect the WAN side
to your network, you cannot ping backwards through the NAT.

You could if you put in a static route on Router 1 describing how to get to
192.168.2.0/24 as long as Router 2 is set to route and is not a NAT.

Yes, Ace makes a good point. I am assuming garden variety SOHO routers, most
of which cannot be straight (non-NAT) routers. Assuming is always a mistake,
of course. In the case pointed out by Ace, the Interface on the near side of
Router 2 would be in the same subnet as the computer and the Router 1, and
the 192.168.2 network would be on the far side. You would need routes
between networks at the appropriate places depending on how your network is
set up.

Thanks for the plug Kurt. I think it would be cleaner that way.

Gordon, for a visual of what this should look like, or just to get an idea
of what it should look like with the routing entries, check out my routing
example:
