Hem d'editar 1 arxiu, i crear-ne 4 de diferents:

'''vi /var/tmp/system.cfg'''
<pre>
ppp.1.name=USUARI
ppp.1.password=PASSWORD
ppp.1.status=disabled
ppp.status=disabled
pptp.1.serverip=IP_SERVER
pptp.status=enabled

</pre>
Un cop editat l'arxiu de configuració, grabem els canvis '''des de l'arrel /var/tmp/'''
<pre> cfgmtd -w -p /etc/ </pre>

Ens dirigim a '''/etc/persistent/''' , per executar 2 lines al arrencar l'antena. Una que aixeca el tunel, i la segona que permet accedir a internet des de l'interficie LAN, fent un MASQUERADING de la LAN

'''''vi /etc/persistent/rc.poststart'''''
