Your config isnt correctly setup.

1. You are using a private subnet 10.10.10.0/24 on your LAN interface FastEthernet0. Doing so, u need the router configure with NAT.

f.e add the follwing commands.
!
Interface Dialer0
ip nat outside
!
and

!
ip nat inside source list 1 interface Dialer0 overload
!
!
access-list 1 permit 10.10.10.0 0.0.0.255
dialer-list 1 protocol ip permit
!

2. U have assigned an ip ifrom /29 subnet to your dialer interface, which is possible but u have to make with your isp if this is the correct ip. It might be possible u can't just pick a random free ip from this range.

If u want the public subnet 217.37.158.128/29 to be directly connected on the LAN interface Fa0, u could use something like this.

f.e add following commands

!
interface Dialer0
ip unnumbered FastEthernet0
!

!
interface FastEthernet0
ip address 217.37.158.134 255.255.255.248
!


Furthermore your post implies you have a problem, if so , it will be usefull to provide more information about what the problem exactly is and what u have tested yourself so far.

greetings,

Fatty

Hi m8.

I've been (trying) to set it up via the cisco sdm.

How do i add the commands you suggested ?

The eventual setup will be your number 2 it should have an external IP that just routes everything to the network. I have brought it home to try and get to grips with it as i couldnt get anything out of it at work

Currently I looks like its connected (at least the sdm shows that) but i cant get any traffic though.

Best,
Chris

Hi brand1068,

Personally, I never worked with cisco sdm, I suggest you just use CLI connecting by console. Just connect a pc from com port to console port on the cisco and use f.e. hyper terminal.

Just copy paste commands below in terminal.

en
config t
!
interface Dialer0
ip unnumbered FastEthernet0
!
interface FastEthernet0
ip address 217.37.158.134 255.255.255.248
!

ps depending on how your ISP has implemented this type of service in their network, u might need to change the ip adress used.

If this still doesnt work u could try the following.

!
interface Dialer0
ip address negotiated
!
!
interface FastEthernet0
ip unnumbered Dialer0
!

In this case your ISP will assign probably the right ip adress to your router using radius.

Let me know if this works.
