VPN series port group issue

Zyxel_Melen

Some of user might encounter this issue for VPN series since it reached its end-of-life status.

If you change the port group setting and vice versa - for example, move P6 from Ge6 to Ge3, and move P6 back to Ge6 - the firewall could allow the traffic on a new zone (or even none) with no firewall rule to allow the traffic.

Solution:

Since the configuration is correct, please reboot the device.
