Q: Can I share the Internet connection on my Pocket PC through Bluetooth/peer-to-peer (P2P) Wi-Fi? That is, can I make my Internet-connected Pocket PC into some kind of a Wi-Fi/Bluetooth Access Point? A: This is a very common question (see for example this, this, this and this threads) and, therefore, worth dedicating a blog entry to it - particularly because, as to now, noone has ever presented a really working proxy solution for sharing the network connection on a Pocket PC (before this tutorial, that is). What's the point in all this, you may ask. Well, it's pretty simple. Let's assume you have two Pocket PC's. One of them is connected to the Internet via, say, Wi-Fi, the ActiveSync Internet pass-through or Bluetooth (say, via GPRS) and, say, your wife/husband/kids/friend is chatting via MSN Messenger or some IRC application on it. You would, however, like to connect to the Internet via the other Pocket PC('s) to browse the Web, using the same Internet connection. You can certainly do this! (Incidentally, this is a very common case in my family. My wife likes chatting via MSN Messenger and, at home, we only have Pocket PC's and GPRS connection (no external Wi-Fi access points, no cable/ADSL connections, nothing) via my mobile phone. The Pocket PC, an iPAQ 2210, she uses for MSN Messenger chat, connects directly to the Net (via BT GPRS) and also shares its HTTP Internet connection by running a HTTP proxy server. This is the HTTP proxy server that I connect to from the other Pocket PC, a VGA Pocket Loox 720, via a Bluetooth Personal Area Network built up between the two Pocket PC's. This way, we can access the Internet using the same GPRS connection at the same time, from the two Pocket PC's, without using any kind of external PC's or other tricks. That is, this solution works beatifully for Internet sharing in my practice.) To share an Internet connection, you'd need operating system-level support for connection sharing as is present in, say, the desktop Windows. It's what is really missing from the Windows Mobile operating system. Fortunately, there're some tricks you can do to be able to access at least the Web from the client machines if you use a HTTP proxy run on the Pocket PC that shares its Internet connection. Note that you won't be able to access anything else: no MSN Messenger, no POP3/SMTP/IMAP e-mail, no multiplayer, TCP/IP and GPRS-friendly games etc. on the "client" Pocket PC's (on the "server" Pocket PC, of course, you can run any Internet client application.). Still, being able to access the Web on the "clients" is a great thing.

Q: How do I reduce my Internet bandwidth usage as easily as possible? I pay a LOT for my non-unlimited GPRS/Wireless data access and I'd like to reduce this. Is there any way of doing this?

A: Sure there are!

Q: What is the host PC's address over a USB ActiveSync connection? I'd like to access my PC from my PDA via USB AS without using its "global" IP address. A: It's always 192.168.55.100.
