# For the UPnP library to function correctly, networking must be configured
# properly for multicasting as described in 
# https://sourceforge.net/p/pupnp/code/ci/master/tree/README.
# Without this addition, device advertisements and control point searches will
# not function.
# However, the route has to be configured once for all UPnP applications
# (igd2-for-linux, ushare, ...) so do not manage UPnP route by default
