Miniupnpd - internal adresses?

Just questions about the miniupnpd in lede 17.01, because there is no hint for the syntax in the 'internal addresses' field. Only the luci failure request pops up and deny saving.

  1. Howto enter a IPv6 suffix like :1:10 to address only this machine that has a static lease from dhcpd6
  2. Howto separate IPv4 and IPv6 in the same field

Must this be done with uci on the commandline? Can someone show a working config file?
