router and server on one linux machine, need help.
Tamer Higazi
I am not a network pro, therefor I ask you gladly for help. I have a
gentoo box with 2 eth0 cards. I have red the gentoo home router guide at:
http://www.gentoo.org/doc/en/home-router-howto.xml?style=printable
but I need to use the machine as router as well as server itself.
I have 2 NIC in the machine (eth0,eth1). On the machine is asterisk and
apache installed. I want to use the machine a router and server as well.
the sip gateway connected at eth0 is configured as:
192.168.1.5 with it's gateway 192.168.1.1 and nothing goes along to
asterisk.
and through eth1 the dialup with pppoe goes there.
I guess, it's not possible to have on the same gateway address a service
running. Could you give me some good advise how to get the thing to run?!

Is this supposed to be your description of the problem? That "nothing
goes along to asterisk"? Your message describes your setup a bit but
doesn't specify what you need help with or what the symptoms are of
your problem.
If you have basic connectivity issues, it helps a lot to tell us what
can ping what (and for a router, to/from which address). It also helps
to paste in interface configurations, router tables, and the like. It
also helps to mention which obviously stupid mistakes you've already
checked for (such as forgetting to turn IP forwarding on). (Otherwise,
10 people will reply "did you turn on iP forwarding?')

It has nothing todo with asterisk. I want the machine to run as router
as well as server at once and I don't know how to set up the machine.
ipforwading is activated and I want the device at eth0 (192.168.1.1) can
access the service. what ipadress will I give the device (connected at
eth0), gateway and subnetmask to make use from the service configured
for the network segment 192.168.0.0 ?!

1) Do the router settings as usual.
2) Do the server settings as usual.
They don't interfere.

Hmm, looks like eth0 is UP but not RUNNING. And it received no packet,
which would be quite surprising on a LAN with other active hosts if the
interface was running fine. Is the ethernet link ok ?

Where does this address comes from ? There is no such 85.0.0.0/8
network, this block is split in multiple networks, and by using this
address and mask you prevent yourself from communicating with them. An
IP address is not necessary for an ethernet interface transporting only
PPPoE.

There should be nothing special you need to do.

You can give at any address inside 192.168.1.0/24 except 192.168.1.1.
It doesn't need a gateway if it's only going to access devices on the
LAN. The subnet size should match the router's.
If you want the other machines in 192.168.1.0/24 to be able to access
the Internet, you'll need to set up NAT on your router. In that case,
192.168.1.1 should be their default route (gateway).

That doesn't seem to make much sense.

on the eth1 interface, eth1 doesn't need to have an ip address.
I have this in /etc/network/interfaces on my router:
auto lo
iface lo inet loopback
# The primary network interface
iface eth0 inet static
address 0.0.0.0
auto dsl-provider
iface dsl-provider inet ppp
provider dsl-provider
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
auto eth1
iface eth1 inet static
address 192.168.0.1
netmask 255.255.255.224
(Debian and Ubuntu use /etc/network/interfaces. Other distros may use
different configuration files.)

I gladly love to thank you. The idea of cancelling the ethenets
interface's IP-Adress where the PPPoE Modem is connected to, solved all
my probelms at all.
I wish you a great day!
