i tried using the same mrtg version as you have (2.9.18pre1)
but still can't get any graph for our tunnel interface.

we are using cisco 3640, IOS Version 12.2(3).
i use cfgmaker as follows:

./cfgmaker --ifref=ip --ifref=descr public at hostname > tunnel.cfg

am i missing something?
would appreciate for any comments or suggestion.
