Connecting a local app over logmein to access a seperate network on remote comp

using logmein i have been able to connect to a remote desktop via the wireless internet connection.

problem is the software i need to access the remote desktops local lan is installed only on my comp.

the remote pcs wireless internet and lan are 2 seperate networks, with the pc being the only device to be able to access both.

I need to be able to attempt connection to the remote lan from the application on my pc.

I was thinking that if i could redirect the program thru the tunnel as if it was being run on the remote pc it would work; however, I have limited experience with tunneling.

Any help would be greatly appreciated!
