Peplink Balance 380 firmware upgrade problem


Hi all. I’ve encountered an issue during upgrading of Peplink Balance 380 firmware and hope you can help me.

I have 2 Peplink Balance 380 configured as HA. The current firmware is 6.2.2, and hardware revision is 5. Based on the support website, the highest firmware I can upgrade to now is 6.3.4.

I’ve tried to upgrade following the guide here, but after upgrading the slave to 6.3.4, I can no longer ping the WAN IP or access the web management of this unit. However, InControl shows the device is online.

I can access the web management via InControl, and thus I used it to downgrade back to 6.2.2, and the WAN IP is pingable and accessible again.

Did anyone encounter this issue before and how should I go about fixing this? Thanks.


The newer firmware allows the slave Balance to use its LAN port to access the internet through the master.


Hi Ron, thanks for your response. Does that mean we can only manage the slave unit via the master in newer firmware? How do I do it? Its in drop-in mode so LAN and WAN1 are sharing the same IP.


Please open up a support ticket here and we shall follow this up via ticket.


Hi. Just did. Thanks!
