If you use gdm as your display manager, it is straightforward to set it
to allow XDMCP enquery. Just enter the configuration mode of gdm and
tick an option in some tag. Then restart gdm daemon. Or look through
/etc/X11/gdm/gdm/conf, just change some lines. That file is
self-explanatory. I don't think think you need extra documentations if
you follow either way above.
The another reason might be the firewall policy. I don't know the
network bwteeen both of your machines. Generally a firewall will block X
traffic as it causes security vulnerarities. This not only involves the
firewall settings on your work machine and your home machine, but also
the firewall policies in between your machines, for example that of your
company, your ISP, etc. You probably can't do much about that.
