Miniupnp config documentation

[professor_jonny]

Is there proper documentation for Miniupnpd around somewhere?

On the forum there is mention of stun server but documentation on the wiki and sources does not mention the configfile format or layout for this in the sources I see this in the init.d the following witch mentions stun and many settings that are not mentioned in the wiki:

I have 4g internet behind a cgnat, I also have a crappy providers modem I have to use as it has a tag locked sim (it will only work if the first digits of the IMEI number match a range stored in the sim).

So I cant stick my sim card into another router so I have set up dmz set to forward all to my openwrt router from the providers router and are trying to get UPNP working.
upnp previously worked withwith the providers router.

	config_load "upnpd"
	upnpd_write_bool enable_natpmp 1
	upnpd_write_bool enable_upnp 1
	upnpd_write_bool secure_mode 1
	upnpd_write_bool system_uptime 1
	upnpd_write_bool igdv1 0 force_igd_desc_v1
	upnpd_write_bool use_stun 0 ext_perform_stun
	upnpd_write_bool ipv6_disable $ipv6_disable
	upnpd_write_bool ext_ip_reserved_ignore $ext_ip_reserved_ignore

I have created a config file with the below does this look correct and do I have to open firewall ports or something?

config upnpd 'config'
	option enabled '1'
	option enable_natpmp '1'
	option enable_upnp '1'
	option download '1024'
	option upload '512'
	option log_output '1'
	option external_iface 'Wan'
	option internal_iface 'Adults_Lan, Kids_Lan'
	option port '5000'
	option upnp_lease_file '/var/run/miniupnpd.leases'
	option igdv1 '1'
	option ext_ip_reserved_ignore '1'
	option uuid '78775f9e-c20d-4a56-943c-6126cbf626d9'
	option use_stun '1'
	option stun_host 'stun.2talk.co.nz'
	option stun_port '3478'

This is the error I get in my kernel log :

I'd like to point out all these issues are resolved now as there is now two versions of miniupnpd in the feeds repo supporting v1 and v2 protocol.

The previous issue was caused by source change and default to v2 protocol and the option in the config to fall back to version 1 actually being ignored by microsoft products because of the string in the headdder says v2 even if the response was in the v1 format.
This is a microsoft issue not properly supporting upnp v2 protocol and as far as I am aware this is not going to change.

I was under the impression I required stun for my ccnat to get the external interface and this is why miniupnpd was shutting down but this was incorect.

Using miniupnpd v1 in conjunction with openwrt release 20 sorted my issue and now upnp works with my xbox and windows 10 computer.
