  The straightforward solution here is to use the "ref" parameter (see the
documentation), which is accessible with \rnode has a special optional
parameter.

\documentclass[a4paper]{article}

\usepackage{pst-node}

\begin{document}

\rput(0,0){\rnode[br]{node1}{\psframebox{$G_1*G_2$}}}
\rput(3,-2){\rnode[tl]{node2}{\psframebox{$H$}}}
\ncline{node1}{node2}

\rput(6,0){\rnode[tl]{node1}{\psframebox{$G_1*G_2$}}}
\rput(9,-2){\rnode[br]{node2}{\psframebox{$H$}}}
\ncangles[angleA=90,angleB=0]{node1}{node2}

\end{document}
