This has me flummoxed, what I am attempting to achieve is have both my main machine and my media center machine sharing my iBurst connection.
Let me first start by describing what is causing my problem.
My two PC's are running windows 7 home premium and XP professional respectively and are connected trough a cross over cable. They are able to ping each other and view shares, access and copy files etc.
Now, the Windows 7 machine is also my main machine with the iBurst modem plugged into the USB port.
The issue is that besides the machines physical LAN connection a secondary LAN connection get's created for the iBurst connection.

So if I view the network map on my windows 7 machine it looks like the following:
iBurst -> Internet Access (random DHCP allocated IP)
Local LAN 2 (iBurst) (Set fixed IP 192.168.0.2)
and then Local LAN (Home network) (Fixed IP 192.168.0.1)
XP Machine (Fixed IP 192.168.0.3 default gateway 192.168.0.1)

Now from what I can see the main issue is that my XP machine cannot connect to Local LAN 2 (even if it uses the same ip range) and this is the main reason I can't simply use ICS, as when I enable ICS on the iBurst connection it uses the local LAN 2 as the default network.

I have also tried setting up a proxy but again the proxy run's on Local LAN 2 as this is where the internet access occurs trough and thus my XP machine cannot see the proxy.

If I am just being stupid please enlighten me, would be ecstatic if it does turn out I am simply going about this the wrong way.
 
Im not understandin where local LAN2 is coming from? Does the iburst modem create a "virtual" lan adaptor? or is this a physical lan port? (so your windows 7 box has 2 physical lan interfaces?)

sounds like a routing issue to me. but cant give you more till i understand what LAN2 is cause it looks odd that its there.
 
LAN2 is a virtual lan adapter created by the iBurst modem.
 
oh yes and as a PS - when using windows ICS, ALL ip addresses must be set to DHCP on all physical interfaces. Windows will assign a static to the correct port on the ICS machine, and the rest will get their ip and default gateway/dns from the dhcp server that fires-up when ICS is running. It will then bridge the interface between iburst and your lan. Doing this and setting Lan2 to DHCP as well might just clear-up your problem.
 
did you put a static ip on Lan2? Dont, if its a virtual one its probably created that for virtual PPPOE to work. Just set it back to DHCP and remember to share the connection on the iburst modem, not the LAN one.

I did enable ICS on the iBurst connection and let it set the IP, the problem comes in that the physical connection on the other LAN card is unable to see the iBurst created LAN connection.
 
but is the other machine set to DHCP? not fixed? it needs to get gateway settings, dns, metrics for the gateway etc?

If I set the second machine to DHCP then it does not get assigned an IP, unless of course I also have to set the home machine's LAN connection to DHCP....
 
ok turn off ICS, set EVERYTHING to DHCP on all computers, all physical interfaces - then re-enable ICS. It will configure what it needs to. Try again.
 
a reboot after all this is done is not bad either, just incase one of the machines times-out with DHCP, or the TCP stack is a problem on the windows 7 box.
 
otherwise failing all of that (and ICS can be an annoyance) try this:

1. Turn off ICS
2. Leave the virtual LAN2 adaptor to DHCP
3. Set the other physical LAN adaptor (the one the crossover cable is in) to 10.0.0.1 and netmask 255.255.255.0 - leave default gateway, leave dns.
4. On the XP machine, set the LAN adaptor to 10.0.0.2 netmask 255.255.255.0 - leave the default gateway, leave dns.
5. Get this program : http://www.winproxy.net/download.html
6. Install it on the Windows 7 machine with the iburst.
7. once done, go to http://10.0.0.1:3129/ and you shuold get a setup page. Just answer the common questions it wants.
8. Your windows 7 machine should browse without any changes to itself.
9. To get the windows XP machine to browse, tell any application like IE, Firefox, MSN etc to use a Proxy Server, and key in 10.0.0.1 as the proxy address and port to whatever you set the Proxy port to in the setup page of Winproxy.

Hope that does something for u.
 
When enabling ICS make sure you do so through the properties of the connection you dial (iburst broadband PPPOE) and select LAN1 as the interface to share through. Windows will then set the IP of LAN1 to 192.168.137.1. Now on the xp machine set the IP to automatic and reboot the PC. When it starts back up you should see an internet gateway in it's network connections and you should have internet access on both pc's.

The thing is how do you change the the interface LAN? If I look in the properties of the iBurst connection LAN 2 is set an it's a text field that cannot be updated....
 
^Right click the PPPoE connection > Properties > Sharing > tick the "allow other users to connect through this computers internet connection" check box > Directly under that select you LAN connection from the drop down menu.

Thanks, I was just being stupid you have to select the LAN before enabling ICS, long day... acting like an end user.
