You can remove ge-0/0/2-ge-0/0/5 from security-zone Internal, these are layer 2 interfaces. Your layer 3 interface vlan.0 is already specified.
Is there a reason you've set MTU on those interfaces? Those settings drop MTU from 1514 down to 1500 and are likely blocking large inbound packets.
For that matter you can delete speed 1g, link-mode full-duplex, and gigether-options auto-negotiation since auto-negotiation is on by default and these are all conflicting settings.
