I used b5 on rb532 with no problems. But b6 make some clients disconects permanently. Problem persist even after downgrade to b5. I had to downgrade do 2.9.40.
Simple setup with wds and all interfaces bridged. No rules on firewall. In my opinion b5 works almost good, but b6 can’t be used for production.
I have a RB532 in my home and with 2.9.x all time i´m was use Gizmo from my Nokia N80ie, now in v3b5 or b6 i can´t connect to Gizmo server…
I am doing NAT masq to my home network… need to do something to SIP work again?
