Right. See if you can work this out...

Firstly, what I want to do:
I want to be able to play music (and possibly video) files on my Axim. The files are stored on my server at home.

Here's my setup:
Starting at the outside, I have a DSL line coming in. That hits my router with an ISP assigned IP address. Once inside, I have 1 items plugged into my router: Another router (wireless this time) and my server. My server's internal IP is 10.0.0.20, the wireless router is 10.0.0.254.
All my other computers, laptops, printer and axim connect wirelessly to the "other side" of my wireless router. They are all on the subnet 192.168.0.x

From my axim, then I can access the internet fine, just like I can from every other computer. I can access shared folders (using Resco) of any other computer on the same subnet (192.168.0.x) but not the server on 10.0.0.20. Although I can ping 10.0.0.20 happily and access the web server running on it. Resco gives me a network resource not available error and Total Commander gives me an error 53.

So, as I couldn't access my music via a network share I thought I'd try a different tack. I've got a web server running on 10.0.0.20 which uses some php scripts to serve up my music as streaming files. I can access these files via Internet Explorer (both internally or externally) from any computer. Pocket Internet Explorer, though, won't load the page. Is it likely that PIE can't cope? Does it have limitations?

I'm going to try reconfiguring my routers so that everything internally is on the same subnet. I've tried once before but everything wireless stopped being able to communicate.

Any other ideas?

Guess your wireless router filtered those netbios packets outside the subnet?

BTW, are you using windows or linux+samba?

The file sharing protocol does not go through routers. Netbois, samba, and the like. I know there is someway because the official corp shared drives are available all over the building but the normal PC shares are limited to the local router. I've tried at home and have not found a way. You would need something like a bridge, annother posibility would be to set up a vpn or tunnel between the servers.... I have done that. Hmmmm.

Aha. Of course!

The netbios packets can't pass though NAT so they don't cross over my "internal" router.

I'm going to have a play tonight and swap some physical connections around.
The whole reason I've got two routers is because one is an ADSL modem router and the other is a cable router with wireless.
What I plan on doing is cable wireless router as a DHCP server but not have it actually doing any NATing. Hopefully then I can get them all on the same 192.168.0.x subnet and not have any problems. I assume the wireless router can route netbios packets from wireless to wired as they don't have to go through NAT.

I'm using simple Windows XP file sharing, btw.

I fixed it :approve:

Thanks for the flash of inspiration.

I now have everything running on the same subnet and it's all very smooth. My wireless router is now just acting as an access point. I'd tried that same in the past but it hadn't worked. Ah well.

Now the only thing I have left to do is somehow disable the power management facility of the Dell Truemobile Wifi card. I can switch it off, but every time I plug it in power management is switch on again
