GPRS keeps connecting when WiFi is available

It is available on the Internet. The LAN has split DNS so that devices
access it through the same name inside and outside the LAN. This was
originally done for Laptop users using RPC over HTTP.

OK so where and what setting should I use for the HTTP Proxy?

Ok, if you go the proxy route, than the proxy should be able to handle
redirection back into the work's LAN. The proxy is configurable on the
device. (For PPC Start->Settings->Connections->Connections (Create/edit my
proxy server). Optional the desktop can try to discover the proxy used by
the PC's Internet explorer, by having the PC's ActiveSync connection
settings in "Automatic" mode.



Ok, a little explanations of what happens here. The device ActiveSync (AS)
will see an "." in the server's name. It will than send a HTTP request to
the proxy with the server's name in the proxy request. The device at this
point doesn't resolve the server's name (just the proxy's name). Now the
proxy server will resolve the server's name to an IP address, which was in
the request. Depending on the topology, if the proxy supports connections
back-into the LAN than it should resolve it to the internal IP address. If
the proxy doesn't support reflection back into the LAN then the IP address
return should be the internet IP.

I'm still having difficulty with this. - This is what I have.

Wi-Fi connects fine to the local LAN and gets an IP address of 192.168.1.n
from DHCP

Start -> Settings -> Connections -> Connections -> Advanced -> Select
Networks
-> Programs that automatically connect to the Internet should connect
using -> T-Mobile Internet
-> Programs that automatically connect to a private network should connect
using -> My Work Network

There are no Intranet exceptions added

Start -> Settings -> Connections -> Connections -> Network Cards ->WIFI ->
Wireless
Network Name: WIFI
Connects to: The Internet

Start -> Settings -> Connections -> Connections -> Network Cards ->WIFI ->
Network Adapters
SDIO WLAN Wireless Adapter
My network card connects to: The Internet (I have also tried work)

What's currently happening is that while there is a WiFi connection
established Activesync works fine to server name
host.localdomain.dom (This can be resolved both on the LAN and from the
Internet using split DNS)
When I turn off WiFi it connects using GPRS (This is how I want it to work)

Also I can browse the Internet using the WiFi connection.
I can also connect to Intranet sites using host.localdomain.dom

But if I try to connect to a host on the local network in the format
http://hostname then it says that it cannot connect with the current
connection settings.

The name server that the DHCP server assigns should resolve addresses of the
form http://hostname as well as http://hostname.localdomain.dom (This works
fine for a standard PC connected to the LAN)

I just can't seem to figure this one out whatever settings I try. I'm
clearly missing something fundamental.

Ok, this is how connection manager works.



The typical device configuration has two networks setup "Work" and "The
Internet"

What happens when a server name is passed to connection manager, it looks
for a dot "." in the name. If the dot is there then connection manager says
it connects to "The Internet", if the there is no dot, than connection
manager says "Work".



Since both of your network settings are setup to point to "The Internet",
http://hostname will fail since there is no "Work" setting (it's a work
address since there is no dot in the name).



There are two ways to fix this. First you need to set your WIFI card to
"Work" since the IP address 192.168.1.n can't possibly be on the internet.



1) If you use a proxy to connect to the internet from your WIFI network
then add the hostname to the exceptions list on the device

2) If your WIFI network doesn't need a proxy to connect to the internet
(typical home setup with a NAT) then check the "This Network connects to the
Internet" checkbox in the "Proxy Settings" and leave the "This network uses
a proxy server to connect to the Internet" unchecked (this for a PPC device
UI, the smartphone's UI is a little different).
