Then you simply need to tag all interfaces with both VLAN's, except for ge-0/0/0 which takes the ISP handoff. An RVI for VLAN 99 is configured to accept a DHCP address from the provider. Assuming you want outbound internet from the trust zone I added an outbound NAT. Your inbound traffic to the three internal IP's will not work unless you configure static inbound NAT to them.
