My broadband connection with static IP address has been installed with a ZTE ZXDSL 831 Aii router by BSNL. But this router has no provision to set NAT rules/Port Forwarding/Virtual Server in its web interface invoked by http://192.168.1.1 whereas the earlier router brands of BSNL like Huawei SmartAX MT 880 and UTStarcom WA3002-G1 both had this feature. Has anyone got a ZTE router, if so what model is it? Is a firmware upgrade required in the case of ZTE? If so, where can I get it from and how to set NAT rules/Port Forwarding/Virtual Server in the ZTE router?

An early reply would be appreciated.
