Further more you don?t need to assign a Gate Way in the Relay Agent NIC. NIC of WAN should be different like 172.16.4.4/16 and then the DG could be the 172.16.4.1 and the DNS 172.16.4.1. You don?t need to specify the Default Gateway of LAN NIC as 192.168.5.3/24. You don?t need to put your scopes into a superscope.
