Basically I want to redisplay my work laptop screen onto my Mac in a window.

At work we use a well-locked down setup - WinXP, Nortel VPN and Tunnelguard
so far I've been unable to use remote desktop to get at it, or even VNC.
TCP-IP is totally tunnelled and guarded!

So I was thinking, could I use some sort of usb connection if such a thing
exists, most likely it doesn't, or maybe I could get to it via Appletalk or
some other protocol?

All this cos I can't be arsed swapping the video lead over......

You can get a Nortel VPN client for the Mac from www.apani.com. Once you
have this installed and set up you can VPN into work and then use VNC to
connect to your work PC or do pretty much anything else that you might
do if you were directly connected to the network.

I've tried that. It connects ok but it doesn't do all the extra stuff my
work VPN setup does, like routing etc, I know I can sort that but I thought
I'd have a look at other options first.

Their OSX client looks awful......

I've also tried Digitunnel which is supposed to work with Nortel but it
doesn't work for me...

I'm not sure what you mean by "routing" in this context. When I connect
to work via the VPN the default routing that I get seems to do the right
thing, i.e. all the network traffic for work (10.x.x.x) goes over the
VPN and everything else ignores the VPN and uses a direct connection. Do
you need to do something other than this ?

I think so - our VPN client is bespoke, a wrapper around the various bits of
COTS software installed on the laptop.

When I use the OSX client I have the tunnel up, but I think I'm still using
the routing table as before cos all I see is my local network. On the lappy
the table is different, local network is totally invisible, I only see work
stuff. It's very clever, and life is too short.

Which is why I thought of alternative ways. I might just try adding the
routes with a script but whilst I'm comfortable with this in Solaris, I'm
not so sure under OSX.

Also at the back of my mind is I shouldn't be hacking like this - but I hate
the frigging slowness of the laptop with XP it's no slouch in spec terms but
by Christ it faffs about loading stuff in the systray and popping up
balloons telling me stuff but hiding the tray icons I want to get info
from....

I might try it from my Sparc box, I know I can do VPN tunnelling on the
interface directly, but I reckon I can't with Nortel switches, seems quite
proprietary...

OK - well I won't pretend to understand what's going on with youe work
network - it sounds odd though. The Apani VPN client works fine for me
with Nortel switches and SecurID authentication and I've never had to
mess with adding routes etc - it all just seems to work.

The only other thing I can think of is that maybe you're using IP ranges
locally which clash with the IP ranges on the remote network, e.g. if
you're using 10.x.x.x on your local router and the remote network is
also using 10.x.x.x ? I use 192.168.x.x for my local network as my
workplace uses 10.x.x.x.

That's it!

I use 10's and work uses 10's. And 192's and 172's....

The desktop's use 10's tho and this is where the clash is. Then we use
Citrix to the other subnets...

I'll give it a whirl.

Cheers!

I don't mean this in a kill-joy sense, but you might want to ask your
work IT department.  They will probably have locked down their network
for a reason, and in some organisations plugging in a "foreign" device
into their network is really frowned upon...Let alone setting up VPNs
into their network...

If you can connect the Mac to their network and get an IP address then
VNC will do the job.

just out of interest, i wonder what would happen if you used the
parallels transporter tool to convert your work laptop windows install
to a parallels image, and then ran it as a VM under parallels?  not
that i'd condone this kind of thing on someone else's network....

Can't happen - PPC land here!

I'm waiting for the new iMac's to come out - better be bloody worth it...
