on our device we configured an ODBC datasource which works fine via
wlan on port 49001.

Now we'd like to use this datasource localy with AS 4.5 too, but this
does not work - I think this is because this port is not forwarded be
AS.

Is there a way to get this port forwarded too?

Thanks
Florian

Hi,
On the PC, ActiveSync uses a separate TCP/IP address and route to get to the
mobile device. So the app would have to listen on the PC's IP.

Also, ActiveSync only supports TCP redirection. There is no UDP support.

Hi Chris,

thanks for your reply.

But we want to have the communication just in the other direction.

- DB is installed on a server in the network
- usually the mobile device connects to LAN over WLAN
- when connected via WLAN the mobile device can connect to the DB on
tcp port 49001 (no udp needed)

And now as a fallback if there's something wrong with WLAN - I'd like
to have the same possibility to connect to the DB. But in this case
with activesync. And for that it seems I have to tell activesync, that
a request coming from the mobile device on port 49001 should be
forwarded just like i.e. if I would open Internet Explorer on the
mobile device.

Is this possible?
Florian

I think that ActiveSync only forwards a couple of TCP ports. Certainly it
does HTTP, SMTP, POP3, but I'm skeptical of random other ports, since
ActiveSync on the desktop would have to really act like a proxy to make that
work. If you used HTTP to get/set your database data (via Merge Replication
with SQL Server, for example), that should work.
