 |
|
Hi!
I've a problem with my network configuration. Perhaps there's someone out there who can help me:
I've a computer [1] with 2 network devices (eth0, eth1) and a second computer [2] with one network card.
computer [1] is connected to computer [2] using eth0
computer [1] eth1 is used for dsl modem connection.
My problem is that internet over the eth1 dsl modem connection is working well, but i could not connect from computer [1] to computer [2] using eth0!
computer [1] has the following:
eth0: 192.168.0.1 -> 255.255.255.0
eth1: 192.168.0.200 -> 255.255.255.128
computer [2] has the following configuration:
ip 192.168.0.3 -> 255.255.255.0
Can anyone tell me why this is not working?
Thank you
Jörg

are you connecting [1] to [2] using a cross-over cable or through a hub?

is this PC2?
my understandng was pc1 had 2 nics and pc2 had 1.
Which of these Ip's belong to who and what one is the dsl modem? Are you belind a router?
If you can clear this up I'll take a crack at it.

@linux_weenie:
I'm connecting computer [1] to computer [2] using a cross-cable, no hub, no switch...
@maletek:
I had some errors in my first post, so I've edited the text above to be correct now (hopefully!)...
I'm not behind a router, but when setting up the dsl connection using 'adsl-setup', i was asked this:
| Code: |
The firewall choices are:
0 - NONE: This script will not set any firewall rules. You are responsible
for ensuring the security of your machine. You are STRONGLY
recommended to use some kind of firewall rules.
1 - STANDALONE: Appropriate for a basic stand-alone web-surfing workstation
2 - MASQUERADE: Appropriate for a machine acting as an Internet gateway
for a LAN
|
and I've chosen '1-STANDALONE'!
I hope this will help you, otherwise ask and I'll try to answer! |

As that's what you're trying to do |

Ok, I've switched, but it's still not working!
Do I have to configure something else? |

Do you have connectivity of any sort from host2 to host1? I.e can you ping it? Also, I assume that both nics (on the different hosts) are on the same subnet, correct?

Those two NICs are on the same network, at least as far as eth0 is concerned. I cannot imagine that is good.

Ok, to clear some things up, Computer [2] is not really a computer, it's my digital satelite receiver running a linux os and having a network connection.
I don't want to access the internet from that machine at the moment. I just want to connect from my computer [1] to the receiver (computer [2]).
But this is not working with Gentoo at the moment. When I've set up the same within WinXP everything works.
Maybe I've something to configure within the /etc/ppp/firewall-masq? But what do I have to configure and how? |
