D-Link router DIR 600M gives error "WAN IP must be on these networks(Hathway router Unlock)

Wan interface or Wan DHCP client not getting ip cannot assing 10.0.0.0 or 192.168.0.0 range static IP.

This Error comes because the router firmware configured to get public ip address, and if the router's wan dhcp client gets a private ip it rewoke the ip or if you do static ip  gives error "WAN IP must be on these networks.

Simply you cannot give a private ip range as wan ip.

For resolving this

You need to UNLOCK  the ISP provided router(Like hathway provided dlink router).

1) Need a Router Firmware (unlocked one).
2)Firmware Update option in Router GUI option (which is DISABLED)
