Metasploit Using Wan Over 3g-Modem Usb?

Hallo, what a great place for study!. Thanks null-byte!

So i have payload and handler that works on LAN. How to make it possible to access everywhere?

Maybe dump question, all i have just 3g usb modem with internet provided by sim card. Dialing internet using wvdial generate these outputs :

--> local IP address 10.49.xxx.xxx

--> pppd: f7f

--> remote IP address 10.64.xx.xx

--> pppd: f7f

--> primary DNS address 112.215.xxx.xxx

--> pppd: f7f

--> secondary DNS address 112.215.xxx.xxx

Is there any method to achive that?, or some refference to make it possible maybe?

Thanks!
