I'm trying to configure a machine with two network cards to share
Internet access to an internal network

the /etc/network/interface is:

# The loopback network interface
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
          address 192.168.0.1
          netmask 255.255.255.0

auto eth1
iface eth1 inet dhcp

The card eth0 is used as gateway on the internal network with static IP
192.168.0.1 and eth1 is connected to the B-890 -53 Huawei modem.

But the modem do not send an IP during initialization.

The IP of modem is 192.168.1.1.

The modem sends the IP address (192.168.0.4) to my laptop by wifi
without problems.

Any suggestions of what I should check?

I'm afraid that I don't understand the problem.  Is this a traditional
async dial-up modem?  If so, I would expect it to be configured with ppp,
its interface name would be ppp0, and it would not be listed in
/etc/network/interfaces at all.  I don't get it.


I'm guessing it's a cdc_ether device - probably running a web and dn
server at 192.168.0.100.  Hopefully the OP will correct my assumption
(Vendor and Product codes from dmesg?).
I'm not familiar with that particular model - but I've had to hack Linux
support for the chipset either side of it (model number).


Kind regards



Dear Scot and Stephen,

I am using this model of modem:

http://www.4glterouter.de/huawei-b890-4g-lte-smart-hub.html
I just tested on another machine and the modem supplied the IP to my laptop via wireless and IP to a computer (with 1 NIC) via ethernet without problem.
Tomorrow I'll change the network card (of the machine with 2 NICs) and test again to see if the problem is the network card. 

Thanks for your attention,
Markos
