  Light-front gauge is the most popular one to work with fundamental
interactions, due to its characteristic maximum kinematical Poincare operators
that it allows. However, it is also known to be one of the trickiest gauges one
can work with for gauge theories, due to its singular nature. So, in terms of
perturbative calculations in the light-front, there are only a few published
and tabulated results for the pertinent Feynman integrals, mostly involving
massless integrals. And the majority of the results given are only for the
divergent parts of them and the complete closed form (or with the finite parts)
of these are not known. In this manuscript, we use the technique of negative
dimensional integration (NDIM) for the simplest of the one-loop massive
integrals as a working bench for massive Feynman integrals in the light-front
and show that novel results for the finite parts not known before are obtained.
