This configuration is simply not valid:
vlan { unit 0 { family inet { address 192.168.5.1/24; } } unit 1 { family inet { address 192.168.5.80/24; } } } }
You are assigning overlapping ip addresses to different interfaces. Once you have a /24 network in use on one interface that same network should NOT be used on any other interface. And any device that has an address in that subnet should be connected to the VLAN assigned to the original interface.
I'm not sure what you are trying to do. But I am guessing you want to put the playstation into a DMZ zone?
If that is true, then you assign a new subnet to the new zone on this interface and address the playstation into this subnet.
