Sometimes when we deploy Ruckus APs remotley over a VPN, they will come up in the Zondirector but will stay on provisioning. then reboot after a bit, and then come back in as provisioning. The reason this happens is that the extra overhead of the added IPSEC header
The cause is the MTU on the Ruckus ZD. Sometime you will have to lower this due to the overhead added to the packet with the IPSEC tunnel.
To lower the MTU of the ZD (First step in troubleshooting APs across a VPN) is to go to configure – APs – and towards the bottom of the page you will see the MTU setting. I would lower this all the way for testing – Lower to 850 or 900. After lowing give the APs 5 minutes to show up in the ZD.
