Basic Static Route Question

We have a 1605 that we are trying the following:

Our ISP is providing a DSL circuit with a single public IP address 69.xx.xx.130.

We would like to assign that address to ethernet1 and then configure ethernet0 with an internal ip address The gateway for the DSL is 69.xx.xx.1

So we set up the two interfaces successfully and can ping each of the interfaces, ip routing is running however we can see to get traffic from the private side to the ISP gateway.

We have tried the following:

ip route 69.xx.xx.0 69.xx.xx.1

ip route 69.xx.xx.1

ip route eth1

All with no luck.

Thanks in advance,

Re: Basic Static Route Question

Before he posted it here Brian posted this same question on the LAN Routing and Switching forum where it has received a couple of responses. I suggest that any discussion of this question be consolidated in the LAN forum.



Re: Basic Static Route Question

Hello Brian,

make sure your configuration looks like this. You do not need a static route to Ethernet 1, since the interface is directly connected:

version 12.2

service timestamps debug datetime msec

service timestamps log datetime msec

no service password-encryption


hostname Router


logging queue-limit 100

no logging console

enable secret 5 yyyy

enable password xxxx


ip subnet-zero

no ip domain lookup


vpdn enable


vpdn-group 1


protocol pppoe


interface Ethernet0

ip address

no ip proxy-arp

ip nat inside

no ip route-cache

no ip mroute-cache


interface Ethernet1

no ip address

no ip proxy-arp

pppoe enable

pppoe-client dial-pool-number 1

no cdp enable


interface Dialer1

mtu 1492

ip address negotiated

ip nat outside

encapsulation ppp

dialer pool 1

ppp authentication pap callin

ppp pap sent-username password 0 zzzzz


access-list 1 permit

ip nat inside source list 1 interface Dialer1 overload !

dialer-list 1 protocol ip permit


ip route Dialer1

line con 0

line vty 0 4




If you cannot get your router to work with this configuration, can you post the one you have so far ?
