fvc:

  • Software versions of OpenWrt/LEDE release, packages, etc.
  • OpenWrt 19.07.2, r10947-65030d81f3
  • miniupnpd - 2.1.20191006-4

I have both native IPv6 (wan_6 virtual interface from pppoe) and 6to4. I need 6to4 to connect to other 6to4 peers which is faster than native IPv6 (and sometimes native IPv6 cannot reach 6to4). /var/etc/miniupnpd.conf generated by /etc/init.d/miniupnpd uses 6to4 instead of native IPv6, the file contains the following lines

ext_ifname=pppoe-wan
ext_ifname6=6to4-wan6

I think it's better to use native IPv6 interface by default.
Additionally, is it possible to add ipv6_disable option to the config? Buggy UPnP clients sometimes put IPv6 address in a IPv4 port mapping request, I'd like to check if disabling IPv6 UPnP would fix it, this problem is mentioned in miniupnp/miniupnp#408
