Imprimir Página - ¿Sabeis que significa esto?

Hola, no se donde poner el post, lo pongo aquí.

He desensamblado con IDA el firmware de mi router.
Si no me equivoco la parte que cambia el firmware con el del fabricante, lo más llamativo es esto:

ip nogateway 1
w dmt2 db tlb 32
ether driver etherppp on
w dmt2 set largeD 2
s cwmp setnovaluetype 1
ether portreverse on
sys cwmp recvtimeout 30
ip nat loopback on
wan dmt2 set pmonoff off
wan dmt eoc dyingasp off
sys dhcpprob no
w dmt2 set lpr off
rt mac2 ssid TP-LINK_
wan fakemac pvc run
wan ghs set multi_number 3 3
ip rip activate
ip rip merge on
ip icmp discovery enif0 off
ppp ipcp compress off
sys wdog sw on
sys quick enable
wan adsl rate off

Esto, en el firmware del fabricante no está, cambia mucho.
Por ejemplo en el firmware del fabricante aparece:

Esto y mucho más es lo que aparece en el firmware del fabricante, pero en el firmware modificado de mi router, no aparece, está recortado y casi no sale nada de lo que hay en el firmware del fabricante.

Nada, como la parte que he puesto al principio, parecen comandos, alomejor sabeis que hacen esos comandos, o bueno, como curiosidad.

Desde luego la parte que dice wan fakemac pvc run , no me gusta nada.

Y gracias a AlbertoBSD, que en un post a comentado lo del ensamblador y he podido hacer esto.

Un saludo.
