[BUG] hostapd - ap_isolation=0 doensn't working

[Fab]

happy new year my friends :)

I am writing about ap_isolate param. Also if you put to 0 the clients
can't communicate each other... (chromecast as an example)

there are lot of post about this issue in the www, some example whit
lot of detail in openwrt forum:
https://forum.openwrt.org/t/clients-in-same-wlan-cant-reach-each-other/2501/74
https://forum.openwrt.org/t/bug-report-802-11s-mesh-v19-07-4/78524/3
https://bugs.openwrt.org/index.php?do=details&task_id=714

the issue is present from several year and no solution is present.

reading lot of posts as workaround you can use for enable/disable ap_isolation
echo 1> / sys / devices / virtual / net / br0 / lower_wlp2s0 / brport
/ hairpin_mode
echo 0> / sys / devices / virtual / net / br0 / lower_wlp2s0 / brport
/ hairpin_mode

 But after that you are no more able to join in the wifi

Do you have any idea?
Thanks a lot for your time!
