private addresses: ping limitations etc...

Hello,

I have the following setup at home:

BelkinWirelessRouter: 192.168.2.1 (internal address)
LaptopSmall WindowsVista: 192.168.2.4
LaptopLarge WindowsVista: 192.168.2.8
PS3 YellowDogLinux: 192.168.2.7

I can browse the web from any laptop or PlayStation3
and each of the three internal computers can ping itself
via its own internal IP address or the default gateway
which is the wireless IP router (which probably also
runs some version of Linux). However while I can
happily browse the web from any of these three
internal computers I am running across the
following problems:

A. No internal computer can ping any other
internal computer other than itself and
the router.

B. No internal computer can ping any other
computer on the internet from the external
interface of the router (which has a proper
IP address as can be seen via traceroute
on Linux or tracert on Windows Vista Home
Premium).

C. I want to shell in from Windows Vista using
putty to my YDL 6.2 Linux PlayStation3
but each time I try the network is
unreachable.

D. I want the PlayStation3 which runs the apache
web server (and during YDL 6.2 installation I
chose not to run the firewall for web requests
to the PS3 so I should be able to use apache
web server on it) to answer HTTP and HTTPS
requests from both the inside (internal network)
and the outside (through the router's external
interface from computers on the network).

What should I do? Should I try and reconfigure
the Belkin Router by connecting to it via
hypertext protocol?

And then I guess I should configure NAT on the
Belkin Wireless router so that any HTTP or
HTTPS requests on it are directed to the PS3?

Thanks,

John Goche

How do you mean it can ping itself through the gateway? If you mean it
can ping itself using its 192.168.2.x address, that won't be going
through the gateway.

How are your firewalls set up on your computers? This sounds like
they're configured to not allow incoming ping requests.

Maybe they aren't allowing anything else in, either.

That's not a NAT issue, that's a port forwarding issue. But yes, you do
need to do that.
