&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== Come configurare il mio router per connettermi alla rete HDSL di Interbusiness ==&lt;br /&gt;
&lt;br /&gt;
Preso da [https://www.recursiva.org/index.php?option=content&amp;amp;task=view&amp;amp;id=40&amp;amp;Itemid=38  www.recursiva.org: mayhem&amp;#039;s document repository]&lt;br /&gt;
&lt;br /&gt;
I parametri necessari per connettersi con successo alla rete HDSL di Interbusiness sono i seguenti:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Configurazione Interfaccia Seriale ==&lt;br /&gt;
&lt;br /&gt;
       interface Serial0/0&lt;br /&gt;
        bandwidth 1536&lt;br /&gt;
        description RETE HDSL Interbusiness&lt;br /&gt;
        no ip address &lt;br /&gt;
        encapsulation frame-relay IETF &lt;br /&gt;
        no ip route-cache &lt;br /&gt;
        no ip mroute-cache &lt;br /&gt;
        no ip proxy-arp&lt;br /&gt;
        no fair-queue&lt;br /&gt;
        no cdp enable&lt;br /&gt;
        frame-relay lmi-type cisco&lt;br /&gt;
       ! &lt;br /&gt;
       interface Serial0/0.1 point-to-point &lt;br /&gt;
        bandwidth 1536 &lt;br /&gt;
        description PVC verso Interbusiness&lt;br /&gt;
        ip address IP_seriale_assegnato 255.255.255.252 &lt;br /&gt;
        no ip redirects &lt;br /&gt;
        no ip unreachables &lt;br /&gt;
        no ip route-cache &lt;br /&gt;
        no ip mroute-cache&lt;br /&gt;
        no ip proxy-arp&lt;br /&gt;
        no fair-queue&lt;br /&gt;
        ip access-group outside in ! access-list che vi protegge e di cui parleremo piu&amp;#039; avanti&lt;br /&gt;
        no cdp enable &lt;br /&gt;
        frame-relay interface-dlci DLCI_Assegnato_da_Interbusiness IETF&lt;br /&gt;
       ! &lt;br /&gt;
       ip route 0.0.0.0 0.0.0.0 Serial0/0.1&lt;br /&gt;
&lt;br /&gt;
La nostra interfaccia seriale e&amp;#039; correttamente configurata. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Configurazione Interfaccia Ethernet ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Per quel che riguarda la scheda Ethernet possiamo avere due possibilita&amp;#039;: utilizzare un IP pubblico (quindi abbiamo un Firewall/Proxy dietroal router - a mio parere indispensabile, e la magistratura sembra concordare con me ;P n.d.r. - ) o un IP privato, ed utilizziamo quindi la funzionalita&amp;#039; di NAT. &lt;br /&gt;
&lt;br /&gt;
Faccio notare che i router preconfigurati da Interbusiness ricadono nella prima ipotesi.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
=== Configurazione con IP pubblico: ===&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
        interface Ethernet0/0 &lt;br /&gt;
         description BAD - Connessa al Firewall&lt;br /&gt;
         ip address ip_address subnet_mask ! IP pubblico assegnato da Interbusiness&lt;br /&gt;
         no ip redirects&lt;br /&gt;
         no ip unreachables &lt;br /&gt;
         no ip route-cache &lt;br /&gt;
         no ip mroute-cache&lt;br /&gt;
         ip access-group inside in ! access-list che controlla il traffico in uscita&lt;br /&gt;
         no ip proxy-arp&lt;br /&gt;
         full-duplex ! se avete uno switch&lt;br /&gt;
         no cdp enable &lt;br /&gt;
&lt;br /&gt;
=== Configurazione con IP privato e NAT: ===&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
        interface Serial0/0&lt;br /&gt;
         ip nat inside&lt;br /&gt;
        !&lt;br /&gt;
            interface Loopback0&lt;br /&gt;
         description Collegamento ed Amministrazione &lt;br /&gt;
         bandwidth 1536 &lt;br /&gt;
         ip address ip_address subnet_mask ! IP pubblico assegnato da Interbusiness&lt;br /&gt;
         no ip redirects&lt;br /&gt;
         no ip unreachables &lt;br /&gt;
         no ip proxy-arp&lt;br /&gt;
         ip nat outside&lt;br /&gt;
         no ip route-cache&lt;br /&gt;
         no ip mroute-cache&lt;br /&gt;
         no cdp enable &lt;br /&gt;
        !&lt;br /&gt;
            interface Ethernet0/0&lt;br /&gt;
         description Connesso alla LAN&lt;br /&gt;
         ip address ip_address subnet_mask ! della vostra LAN&lt;br /&gt;
         no ip redirects&lt;br /&gt;
         no ip unreachables&lt;br /&gt;
         no ip proxy-arp&lt;br /&gt;
         ip nat inside&lt;br /&gt;
         no ip route-cache&lt;br /&gt;
         no ip mroute-cache&lt;br /&gt;
         ip access-group inside in ! access-list che controlla il traffico in uscita&lt;br /&gt;
         full-duplex ! se avete uno switch&lt;br /&gt;
         no cdp enable&lt;br /&gt;
        !&lt;br /&gt;
        ip nat inside source list 110 inside interface Loopback0 overload&lt;br /&gt;
        access-list 120 permit network_address subnet_mask any ! solo gli ip della vostra LAN&lt;/div&gt;</summary>
