WAN1 and WAN2 Interface can use Assist to enter the data.
After setting, there will be two subnet in LAN: 192.168.1.0/24 (default LAN subnet)
and 162.172.50.0/24. So if LAN IP is:
˙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)(Figure2-9)
