Hi all.
I am in the process of trying to set up a a wirless router so I can get
rid of some cables and stuff running all over the place

I having a real problem with getting it to work though
(ive googled and man'd and faq'd)
Here is the issue in a nut shell

The server A has two nic, one ext and int
on server A I can surf and do everything fine

I can login from a laptop via int_nic (wireless)
and everything works fine

but once I try to acutally surf from the laptop, nothing happens

i ahve a few questions

Since int_nic is a dhcpd server, should I just be naming in form the
192.168.1.0/24
or should it be a separated subnet 192.168.2 say.

Another way of stating this is, should the int_nic and the dhcpd
assigned IPs be on the same net or on different subnets?

It's a little difficult to diagnose such problems remote -- so I won't
be trying that.

But what I will say is -- there's more than 1 way to set these things up.

Presumably you config the wifi router using a web interface. I expect
that is working OK. You then attach one of the "internal" ports to
your desktop box (say). I presume your desktop box has a fixed IP & MAC.

It then should be a matter of getting your laptop to connect to the right
SID (set on your web interface to th router) and simply try to "ping"
(or whatever) the fixed IP of your desktop box.

If you can get THAT far, you might try enabling dhcp on the router and
allwoing it assign IPS to connecting laptops -- but I'd not be trying that
first up.

You should also setup a screen (semi permanently to tcpdump anything
soming headed toward the desktop from the router. You can setup
tcpdump to listen only for packets from specific subnets, if there is too
much traffic on the relevamt wire.

Oh yes, get some vallium. And welcome to wifi.

1. thanks for the reply
2. It turned out that I didnt understand routing as well as I thought I
did
3 ie Routing only defines the next hop!!!!!!
4. so when my laptop got its default gateway, it was a nic complete
different thatn the only one it knew about so I when ahead and defined
it and voila it worked
ie


C(laptop) ---> B(Wifi CARD) ---> (ext-if)

I was defining the laptop's gateway as ext-if, which it had no way of
contacting
