˙192.168.1.xx, it must use NAT Mode to access to the Internet. (In Policy it only can setup to
access to Internet by WAN2. If by WAN1 Routing mode, then it cannot access to Internet by its
virtual IP)
˙162.172.50.xx, it uses Routing mode through WAN1 (The Internet Server can see your IP
162.172.50.xx directly). And uses NAT mode through WAN2 (The Internet Server can see your
IP as WAN2 IP)
