Can't bridge tethered Huawei Ascend M860 out of Win 7 laptop

I am using PdaNet to tether my Huawei Ascend M860 to my Lenovo R500 laptop. That internet connection works fine and is labeled in network connections as "PdaNet Modem".

I am trying to bridge that connection out, by way of the LAN ethernet port. The "Bridge Connections" option is not available when both "Local Area Connection" (my laptop's broadcom adapter ethernet port) and the "PdaNet Modem" are highlighted and either is right clicked for pull down menu options. (see attached pics).

When just "Local Area Connection" is highlighted and right clicked, the pull down menu option shows, "Bridge Connections" and asked for two LAN or high speed internet connections.(see attached pic)

Does Win 7 NOT consider my "PdaNet Modem" a LAN connection? Obviously it is not a high speed connection.

Irregardless is there a way around this so I can used my tethered Huawei for internet and bridge it out by way of my ethernet port?

Thanks Eto

Additional Info . . .

Why does windows call this a modem connection? It utilizes a USB port where other internet LAN devices are configured to use an internet connection source!

Or is this "Modem" classification set by the PdaNet software? There's no "dialup" involved, there's no "modem-negotiations" and there's no "user/password" required. This (It) is a direct internet connection.
