  Pure glue QCD is formulated on a 2+1 dimensional transverse lattice, using
discrete light-front quantization. The transverse component of the gauge fields
is taken to be compact, but in a linearized approximation with an effective
potential. The (rest-frame) $Q\bar{Q}$ potential is evaluated numerically using
Lanzcos matrix diagonalization. We first discuss the strong coupling limit
analytically and then present numerical results beyond the strong coupling
limit. The physical origin of confinement on a transverse lattice depends on
the orientation of the external charges: For longitudinally separated charges,
confinement arises from the instantaneous Coulomb interaction and for
transversely separated quarks a string of link-fields forms. In the general
case one obtains a superposition of both effects. Despite the asymetry in the
microscopic mechanism, already a very simple ansatz for the effective
link-field potential provides an almost rotationally invariant $Q\bar{Q}$
potential. The momentum carried by the glue depends strongly on the orientation
of the external charges, which might have observable consequences.
