Hi Jim,
The ACL setting referred to here is for the lwapp2scg conversion utility that allows ZD-based APs to connect to the SZ. In the SZ CLI, you can change this setting:
vSZ# config
vSZ (config)# lwapp2scg
vSZ (config-lwapp2scg)# policy accept-all
If the problem persists after this, try (just for confirmation) to change the policy to "accept" and then enter a rule (vSZ (config-lwapp2scg)#
acl-ap...) to add an allow rule for that specific AP.
Also, can you share what build you are working from?
thanks,
Marcus
