Hi,

Here is how I configured a N900 as a router when connected to my laptop with the USB cable in "PC Suite" mode.

on the N900
/etc/apt/sources.list
deb http://repository.maemo.org/extras-devel/ fremantle free
apt-get install iptables
http://wiki.maemo.org/Kernel_Power#I...el_from_extras
apt-get install kernel-power-settings
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
iptables -t nat -A POSTROUTING -o gprs0 -j MASQUERADE
cat /etc/network/interfaces
iface usb0 inet static
address 192.168.3.15
netmask 255.255.255.0
ifup usb0

on the laptop
sudo ifconfig usb1 192.168.3.14
sudo route add default gw 192.168.3.15

Thanks, what a useful first post!

It might be good to put this somewhere on http://wiki.maemo.org/ for better posterity.

It's possible to do this with the Nokia PC Suite as well - the "One Touch Access" functionality seems to work with the N900, altho I've only tried it on Windows XP.

Updated the wiki page with a mention of same.

I believe this is a yes and no. Yes, Nokia PC suite allows to connect a PC to the internet using the n900 as a GPRS/HSDPA modem, but I don't find anything allowing use of the n900's wireless card for this purpose.

Ioic's method allows both viz the following code:
Code:
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
iptables -t nat -A POSTROUTING -o gprs0 -j MASQUERADE
If I am wrong please provide pointers...

In my case I had to use usb0 instead of usb1 in:
sudo ifconfig usb1 192.168.3.14

But works great, thanks!

Added dnsmasq to the mix and it can fully act as a router servicing both DHCP and DNS to the PC making network connection fully automatic on the PC side.

And to finish it making the setup permanent I added the following in /usr/sbin/pcsuite-enable.sh:

Code:
ifup usb0
echo 1 >/proc/sys/net/ipv4/ip_forward
iptables -t nat -F POSTROUTING
iptables -t nat -A POSTROUTING -j MASQUERADE
dnsmasq -I lo -z -a 192.168.2.15 -F 192.168.2.64,192.168.2.127
got the idea of /usr/sbin/pcsuite-enable.sh from a related wiki post.

/etc/network/interfaces is configured like discussed before:

Code:
auto usb0
iface usb0 inet static
        address 192.168.2.15
        netmask 255.255.255.0
        # gateway 192.168.2.14

Thanks folks. I just did this with only extras-testing enabled, so it may be wise to removed the advice to enable -devel from the wiki page?

BTW, I previously found usb0: would not work at the same time as a usb or bluetooth PPP connection (/dev/ttyACM0 or rfcomm0) through the N900. Anyone know why?
That would have been better, as the PC gets a public internet address instead of NAT, while still being connected to the n900.
