I have a 3G modem-like device (eMobile's D01NX, PC card style, for any Japan nerds out there) that I use to connect my PC to the Internet.

I'd like to bridge this connection with another computer either via an ad-hoc wireless network, or a simple cross-over cable (either are options).

However, when I open "Network Connections", I do not see the PPP connection (otherwise I could click both and bridge). I believe this is because there is software (provided by the vendor) that is handling the card directly and registering a PPP connection dynamically.

When connected, an ipconfig at the command line yields:

Ethernet adapter wireless:

        Connection-specific DNS Suffix  . :
        Autoconfiguration IP Address. . . : 169.254.5.169
        Subnet Mask . . . . . . . . . . . : 255.255.0.0
        Default Gateway . . . . . . . . . :

Ethernet adapter lan:

        Media State . . . . . . . . . . . : Media disconnected

PPP adapter {B59EEDDE-A22B-48DF-93E5-04842B641257}:

        Connection-specific DNS Suffix  . :
        IP Address. . . . . . . . . . . . : 114.xx.xxx.xx
        Subnet Mask . . . . . . . . . . . : 255.255.255.255
        Default Gateway . . . . . . . . . : 114.xx.xxx.xx

(I've commented out my IP address for privacy reasons, but what does appear there is a functional Internet IP address.)

When I disconnect the adapter with the vendor software, the PPP connection disappears completely from the ipconfig list.

Any ideas on how to do this?
