That might be a good place to start.

OK: I donât quite think I understand this. Unless this is to be a
standalone network (and you mention Google, soâ) somethingâs got to have
a connection to the Internet.
If the laptop has a connection of its own to the Internet (say a 3G
dongle or a USB ADSL modem), what you would want is something like this:
Internet
^

laptop
/ \

192.168.0/24 192.168.1/24
Then all the devices on 192.168.0/24 should have 192.168.0.140 as their
gateway (assuming thatâs the laptopâs IP address). Youâd probably also
have NAT already turned on.
If, on the other hand, youâve got a separate router (say an ADSL
router), then what youâve got is something like this:
Internet <ââ> router <ââ> 192.168.1/24 <ââ> laptop <ââ> 192.168.0/24
Then youâve got a problem for all the other devices on 192.168.1/24.
They know that anything on 192.168.1/24 is local, and should just be
sent on the local network. They âknowâ that anything else is on the
Internet, and should be sent to the router.
So, in particular, anything on 192.168.0/24 isnât local to them, and
gets sent to the router, not the laptop.
What you need to do is to tell everything on 192.168.1/24 to use a
static route: packets to 192.168.0/24 should go to the laptopâs IP
address.
You might find it easier to get this working with static IP addresses
first, then replicate that with DHCP.
Hope this helps,
James.
