In the direction of the front or forward.

Vanward is formed from "van" (from Old English "fana", meaning flag or banner) and "-ward" (meaning in the direction of). The word "vanward" refers to the direction of the front or leading position, often associated with a banner or flag leading the way.
Think of a 'flag' ('van') leading the way 'forward' ('-ward') — that's why vanward means towards the front.
