Huawei B970b (Smartone Vodafone Wifi Router)

Before I subscribe the Smartone Vodafone Home Broadband service, I've serviously try to seek some official answer the following questions:
1. Will the router get a public IP address?
2. Does the bundled WIFI router allow me to configure port forwarding?

And the official answer is NO!

But the fact is, YES! The router is Huawei B970b, as there is not much information on the Net at this moment, I'd share information gathered so far. Before is a summary followed with command line output capture (Yes, I can get the shell  access on the router easily)!

Below is summary of import points
1. I do get a public IP!
2. The default router admin software (web-based) allow you to configure port forward
3. In addition, you can also configure DMZ server, MAC filter, DynDNS setting.
4. Telnet port (23) is opened by default (login with the admin account and you get a busybox)
5. It use dnsmasq and iptables

The following is the information I gathered after I gain root access:
