I forgot something. You say you are using the WAN port on the WAP? I
thought that port is only used for the internet connection itself
(like a adsl modem). Try using one of its regular ports. This
probably will break your VPN.<!-- ~MESSAGE_AFTER~ -->

that's the problem. Don't connect to the WAN port, connect to one
of the normal network LAN ports.

The WAN port is supposed to isolate and firewall the wireless and
LAN ports from the WAN port. Granted, it is supposed to allow LAN
and wireless to see anything on the WAN, but in practice they are
two seperate networks. So connect your LAN to a LAN port on the
DI614 and you should be OK.

That's the way I run.

I had to turn off the DI-614's DHCP server. And the DI-614 does not
do DHCP client on the LAN ports, nor does it do NTP. So it doesn't
get an IP address, and it doesn't get the time for its logs. Oh
well. You don't need those to function as a "hub".

Nope. VPN should be fine unless the linksys breaks it.

Hi Mr_Scary (Cool handle!!)

Thanks for the fast reply,

I cannot ping any of the wired machines from the laptop it does not
work the other way around either. I did setup the DNS ip address on
the WAP to point to my adsl providers dns machines and now I can ping
and connect to the internet (Yahoo et. al.)
I can also connect to work thru VPN from the laptop as well as from
the wired machines. I think you are right in saying that there is some
firewall mechanism on one or both the router/gateway devices that
inhibit the connection.
The obvious Q at this point would be how do I turn off the firewall
mechanism on the WAP. Is this something that is even possible?? or do
I have to buy a plain wireless access point device to achieve this
type of topography??

Again, thanks for the fast reply

Like I alluded to in my second post and what Sylvain mentioned, try
connecting the WAP to the linksys without using the WAN port (use one
of its regular ports).

To view firewall config simply access its html interface by browsing
to (probably) 192.168.0.1. The linksys should also have an IP. Make
sure you know what they are (i.e. so you know what device you are
looking at; the linksys also has a web interface).

I would disable any DHCP server which both these devices usually have
on by default and configure your clients manually.

Sylvan & Mr_Scary

You guys are brilliant, I just swapped the connection from the WAN
port to one of the LAN ports and, boom, the laptop started to connect
to LAN and the internet without a problem.
This is absolutely amazing. I've been bouncing (boink, boink, ...) my
head off the wall for the past two weeks trying to figure this one
out.
One thing though, I had to change the ip settings on the laptop from
dhcp to fixed internal ip to get the VPN to work, I believe that this
is a linksys idiosyncracy, but this was negligible.

Once again thank you very much.

fwiw, that same "one thing" was explained to you in sdb's last paragraph...<!-- ~MESSAGE_AFTER~ -->
