I have a ZTE MF823 3G modem connected to Windows XP Professional. It is seen by the system as local area connection with IP 192.168.0.1 and netmask 255.255.255.0.
I'd like to share this connection to another computer, with Lubuntu, over ethernet. Unfortunately WinXP requires the eth interface to which other connection is shared to have IP 192.168.0.1 -- so it requries me to have two different network interfaces working in network with colliding addresses.
Is there any possibility to share a network connection with addresses 192.168.0.0/24 to another network (eg. 192.168.1.0/24) and not the other way around?
Trying another approach I managed to change ZTE modem's IP from 192.168.0.1 to 192.168.1.1 -- there is a simple Linux on it, so I could telnet to it, login as user: root, pass: zte9x15 and via ifconfig usb0 192.168.1.1 netmask 255.255.255.0 change the IP, then changed Windows connection config to use 192.168.1.2 and I could share that over 192.168.0.0/24-LAN. But after reboot ZTE modem came back to IP 192.168.0.1 and all the sharing stopped working.
I am considering permanently changing modem's local IP, however I do not know how to do that. I did cat /etc/network/interfaces and got result:
root@9615-cdp:~# cat /etc/network/interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
auto lo
iface lo inet loopback
# Wireless interfaces
iface wlan0 inet dhcp
wireless_mode managed
wireless_essid any
wpa-driver wext
wpa-conf /etc/wpa_supplicant.conf
iface atml0 inet dhcp
# Wired or wireless interfaces
auto eth0
iface eth0 inet dhcp
iface eth1 inet dhcp
# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
iface usb0 inet static
address 192.168.7.2
netmask 255.255.255.0
network 192.168.7.0
gateway 192.168.7.1
# Bluetooth networking
iface bnep0 inet dhcp
And ifconfig -a gives output as below, so it seems that that the /etc/network/interfaces is unrelated and I do not know how to change the network and modem adresses for good. So I'm looking for any solution to share network over differently-adressed-LAN or to permanently change ZTE modem's address. Thanks for all advices.
Here's the ifconfig's output:

It doesn't solve my problem, because the article doesn't (despite what is written) apply for Windows XP.
As one can see here, on WinXP it is (probably) impossible to change ICSharing addresses: http://answers.microsoft.com/en-us/windows/forum/windows_xp-networking/changing-the-default-network-number-on-winxp-ics/ac6ab06e-d854-e011-8dfc-68b599b31bf5
So I still need a different fix.
