I have been working in the Mobile CRM arena. The company I'm working for has a corporate LAN, in which a CRM server lies. I need to be able to perform remote access connections from my handheld (running Windows CE) to that LAN, by using VPN connectivity.
Now the big question: This corporation is running Nortel Contivity VPN routers to allow VPN LAN connectivity. I sincerely haven't heard of any Nortel VPN client for Windows CE.
Do you know if it would be possible to use some other kind of VPN client to connect to a Nortel
Alternatively, you might consider an SSL-based remote access to get broader device support. Companies like Neoteris and Netilla provide a VPN gateway that uses SSL instead of IPsec. The benefit is that you don't need a client, just a Web browser. These products do a great job of mapping from HTML on the client side to the applications and servers on the LAN side -- a process called reverse proxy.
I'll keep an eye on other CE solutions as they become available.
Hope this helps,
