Making assumptions about how you're using this hostlist,
which you still did not tell us:

hostlist auth_hosts       = !127.0.0.1 : !localhost : \
                            *.vpn.tu-berlin.de : \
                            !130.149.0.0/16 : \
                            !141.23.0.0/16 : \
                            *
