Hey Simon,

I gave your config a try and your issue is most likely a config error.

As soon as you drop the "list ifname 'freifunk'" from the notrust bridge + the "option isolate '1'" from the wifi-iface, clients can ping each other.

The "freifunk" wireless interface is added automatically to no trust bridge due to the "option network 'notrust'" in wifi-iface config. Adding (or try to add) it twice causes the issue.

For reference, the relevant part of my test config:


/etc/config/network 

config wifi-iface
	option disabled '0'
	option ifname 'freifunk'
	option device 'radio0'
	option network 'notrust'
	option mode 'ap'
#	option isolate '1'
	option encryption 'none'
	option ssid 'berlin.freifunk.net'
#	option hidden '0'
#	option wpa_group_rekey '0'
#	option disassoc_low_ack '1'
#	option wmm '1'
#	option ieee80211r '1'
#	option mobility_domain 'd0d0'
#	option pmk_r1_push '1'
#	option nasid '000000000000'
#	option r1_key_holder '000000000000'
#	list r0kh '68:72:51:1B:74:89,6872511B7489,${freifunk_roaming_key}'
#	list r0kh '00:27:22:ca:ff:20,002722caff20,${freifunk_roaming_key}'
#	list r0kh 'dc:9f:db:58:ca:a2,dc9fdb58caa2,${freifunk_roaming_key}'
#	list r0kh 'e8:94:f6:e5:70:00,e894f6e57000,${freifunk_roaming_key}'
#	list r1kh '68:72:51:1B:74:89,68:72:51:1B:74:89,${freifunk_roaming_key}'
#	list r1kh '00:27:22:ca:ff:20,00:27:22:ca:ff:20,${freifunk_roaming_key}'
#	list r1kh 'dc:9f:db:58:ca:a2,dc:9f:db:58:ca:a2,${freifunk_roaming_key}'
#	list r1kh 'e8:94:f6:e5:70:00,e8:94:f6:e5:70:00,${freifunk_roaming_key}'


/etc/config/network

config interface 'notrust'
	option type 'bridge'
	list ifname 'eth0.3'
	# list ifname 'freifunk'
	# option force_link '1'
	# option hairpin '0'
	# option mcast_to_ucast '1'
	# option igmp_snooping '0'

	option netmask '255.255.255.0'
	option ipaddr '10.7.12.5'
	option broadcast '10.7.12.255'


Wireless AP as bridge member is the LEDE default config. Using the default config, wireless clients can ping each other as well. Please try with the default config first before reporting issues. Add you custom setting step by step to provide us a hint which config introduces an issue.
