Very Computer

Hi,

Our network looks like this:

Win95   <->   Linux   <->   Internet

Connecting/PINGing from the Linux computer to the Internet works great,
connecting/PINGing from the Win95 computer to the Linux computer works
great as well, but connecting/PINGing from the Win95 computer to the
Internet does NOT work. Everything seems to be set up correctly - the
two computers are using the TC/IP protocol to exchange data.

Please help... there is no answer to this question in the Ethernet faq!

Thanks a lot!

A.M. Arzt

Do you have the IP address of your Linux box in Win95's Networking
setup as its gateway address?  (Control panel / Network / TCP/IP
Properties / Gateway)

Is the Win95 box's IP a valid one as far as the Internet knows? (I.E,
will the machine you're pinging *to* know to route the packets *back*
through the Linux box?)

If you're trying to ping a machine name (as opposed to an IP address),
is your nameserver setup correct under Win95?

Any of them would do it.

Good luck,
-Dave

:   Well, first things first.  Is IP Forwarding compiled into the kernel and
: configured properly?  Also, unless you have an assigned IP address for your
: win95 machine *that your ISP know about and will route to* you'll need to
: set up IP Masquarading as well.

Actually, if you use SOCKS, you don't need IP forwarding, nor do you need
for your ISP to know about any of the machines you've got* off
your connection.  You need *one* IP address for the Linux box - that's
all.  Any other boxes you have hung off that you can give 192.168.XXX.XXX
addresses (or similar) - there's a list of IP addresses that anyone can
use, in an RFC somewhere.

I hide three machines behind one Linux server that is connected to the
Internet.  My ISP only knows (or cares about) that one that he's assigned
an IP address to.  The other three machines use SOCKSified clients
(Netscape browsers, telnet, etc.) and they work just fine.

Of course, the connection to the outsie world gets a little slow at
times, but that's what I get for not being ruthless enough to be able to
avoid a personal T1 to the net ;)

However, even when you get that working, understand that SOME things
will NOT work from the Win95 to the Internet.  Among them, PING and TALK.
