Ive just got a 4150 and i love it! I have it set up so i can sync with Exchange on my SBS2003 server when im on the LAN through wireless and that works a treat.
I also have bluetooth set up to my nokia 6600 so i can dial up to Freeserve and access the internet while im out of the office.
Now, my ADSL router in the office supports VPN (L2TP and PPTP). I can connect my laptop on dial up to freeserve, open up a PPTP connection to the router and i can access the office LAN and sync outlook to the exchange server. No problem!
I want to be able to do this to sync my 4150 as well. I have added the VPN info into the work settings, but i dont seem to be able to get a connection to the office LAN and the exchange server when dialing up via my phone.
Has anyone managed this? Any tips and help would be great!
