internet via a computer gateway?

[btooth]

we are trying to set up a internet connection for a bluetooth device but going through a PC.

what we have is a PC running XP with internet connection via broadband, and then the other other end with a bluetooth connection to a PDA (T3). we are able to establish connection between the PC and internet, and connection between the T3 and the PC. but we aren't able to connect to the internet from the T3 via the PC. i tried bridging and that didn't work. is there something that we are missing?

any bluetooth expert out there?

Well I'm no expert but I'll take a crack at it.

From what I understand you need a PPP server for your computer. One of the recommended ones is Mocha PPP, available as a download Mochasoft.dk

You set up the software with device as Windows CE, port whatever your Bluetooth is on, and baud rate 115200.

On the T3, create the connection to the PC using its network name.
Create a new service (username and password blank) connecting to the server name set in Mocha.

Good luck with it.

in the end, we succeeded. but we had to resort to some probably questionable settings...

what we did was we managed to get the XP PC and PalmOS T3 talk to each other via Bluetooth. that part was rather painless as the bluetooth detection is quite automated. on the PC side, we need to specify sharing of the PC's internet connection in the Bluetooth setup. but that was all good.

the PC's connection via 802.11b is trivial so i am not going to go into that.

the part that is tricky is how to get all the T3's internet requests to go to the wireless interface of the PC. so we had to set up "Internet Connection Sharing" from the XP network properties. that's the setting which ppl use to make the PC the NAT for a private network.

then we need to setup the bluetooth network as the private network. this part is kinda tricky. as i have a private network set up as 192.168.0.0 between my netgear router and my PC, i have to setup the bluetooth side as 192.168.1.0 so the routing table don't clash.

so i had the PC's bluetooth interface's IP address hardwired as 192.168.1.1 and then i had to go into the T3 and hardwired the bluetooth interface's IP address to 192.168.1.2. and whoala! we were surfing CNN.com!

that took us a bit more than an hour.

throughout that evening, we had a little wireless party, 3 laptops, 3 Palms. and we were beaming pictures and online chatting and surfing the web and playing games. and some good chinese takeout. rather educational evening!

when i managed to get the bluetooth connection between my laptop and the T3 setup. it was automatically configured as a PPP connection. there are quite a few service that the bluetooth protocol defined and was available to the T3. eg. things like web (http) and then printing services too. i guess one useful thing is to allow the T3 to share the printer of my desktop by sharing it to the notebook.

so we will have T3->notebook->Desktop->printer.

i am getting dizzy.

If you're using cable or DSL, or even connected via Ethernet at a university, you can use a router to protect your computer from access by others. The router gets the IP address from your Internet service provider. Then, it creates a local area network to which your computer belongs. The result: you can get to the Internet, responses can get back to you (because the router keeps track of your requests and responses to it, but computers on the "other side of the router" can not initiate connections to your computer — the IP address they see is the router's!

To set up a private network first of you have to have some systems present near you. Then only you think for setting up an network connection.
