<br>
after some challenges with installing the necessary modules for the new
Sierra Wireless MC8700 embedded modem on ALIX 6b2 I got the modem now
up and the new Direct IP interface working. <br>
<br>
Here is briefly how it was done, and there is two questions left to you
gurus too.<br>
<br>
So, if Direct IP is new to you too, its is a very very cool new feature
in the newest Sierra modems. You can connect directly to 3G modem
without using ppp at all!<br>
<br>
Here is the story:<br>
<br>
1. I installed new sierra and sierra_net modules to Voyage, and they
seem OK:<br>
<br>
voyage:~# lsmod |grep sierra<br>
sierra_net 8580 0<br>
usbnet 12040 1 sierra_net<br>
sierra 11144 0<br>
usbserial 24368 1 sierra<br>
usbcore 103996 7
sierra_net,usbnet,sierra,usbserial,ohci_hcd,ehci_hcd<br>
<br>
2. The new usb0 interface gets up and IP addresses from the operator:<br>
<br>
voyage:~# ifconfig usb0<br>
usb0 Link encap:Ethernet HWaddr ba:36:0c:7f:01:07<br>
inet addr:85.77.195.36 Bcast:85.77.195.36
Mask:255.255.255.255<br>
inet6 addr: fe80::b836:cff:fe7f:107/64 Scope:Link<br>
UP BROADCAST RUNNING NOARP MULTICAST MTU:1500 Metric:1<br>
RX packets:207 errors:0 dropped:0 overruns:0 frame:0<br>
TX packets:380 errors:0 dropped:5 overruns:0 carrier:0<br>
collisions:0 txqueuelen:1000<br>
RX bytes:43510 (42.4 KiB) TX bytes:30174 (29.4 KiB)<br>
<br>
3. As the last step I changed NAT'ing eth0 from eth1 to usb0 and after
that it works nicely.<br>
<br>
<br>
Then the questions:<br>
<br>
1. At boot there is a notification about invalid interface number and
missing interface number </font></small><small><font face="Verdana">(lines
2 and 3 below)</font></small><small><font face="Verdana">. Is this a
problem and is there something I could do?<br>

done.<br>
<br>
<br>
2. Would it be possible to configure ADSL and 3G (eth1 and usb0) to be
used simultaneously as each others backups? I.e. in case of one
interface failing the other one gets active and returns when the
preferred interface is up again.<br>
<br>
