Tunnel over Cellular Interface Configuration

The following example shows how to configure the static IP address when a tunnel interface is configured with the ip address unnumbered <cellular interface> command:

interface Tunnel2

ip unnumbered Cellular0 tunnel source Cellular0

tunnel destination 128.107.248.254

interface Cellular0

 

bandwidth receive 1400000

 

ip address 23.23.0.1 255.255.0.0

 

ip nat

outside

 

ip virtual-reassembly

 

encapsulation ppp

 

no ip mroute-cache

 

dialer

in-band

 

dialer

idle-timeout 0

 

dialer

string dial<carrier>

 

dialer-group 1

 

async mode interactive

 

no ppp

lcp fast-start

 

ppp chap hostname <hostname>

*** gsm only ***

pppchap password 0 <password> ppp ipcp dns request

!traffic of interest through the tunnel/cellular interface ip route 10.10.0.0 255.255.0.0 Tunnel2

Configuration for 8705 modem

The following shows how to configure an HSPA+ modem:

chat-script hspa "" "AT!SCACT=1,1" TIMEOUT 60 "OK"

interface Cellular0 ip address negotiated encapsulation slip dialer in-band dialer pool-member 1 dialer-group 1

async mode interactive

interface Dialer1

ip address negotiated ip nat outside

ip virtual-reassembly in encapsulation slip dialer pool 1

dialer string hspa dialer-group 1

ip nat inside source list 1 interface Dialer1 overload ip route 0.0.0.0 0.0.0.0 Dialer1

access-list 1 permit any dialer-list 1 protocol ip permit
