VERY basic help needed (SOHO 91)

[phoneguy2286]

I have a SOHO 91 that I wish to use for very very basic home use. I am not familiar with IOS at all, and this is my first attempt. I have successfully hosed the GUI interface, and have to do everything command line. I have been able to initiate DHCP, but still having a few problems.

I can't get the DNS to work properly, and it looks like every time I reload the router, the interfaces drop and don't come up. Does anyone have a very basic config, or can you look through my config and give me some pointers?

THANKS! If anyone needs PBX assistance, I can possibly return the favor.

What is interface ethernet 1 connected to? What is doing NAT? Also, post a sh ver...
router(config)#ip route 0.0.0.0 0.0.0.0 e1
router(config)#ip name-server x.x.x.x

Burt

 

[phoneguy2286]

Eth 1 is the WAN connection to a DSL modem.

there should be no NAT.
ip name server?

see... I really don't know what I am doing.

thanks!

 

[phoneguy2286]

can you explain ip name-server x.x.x.x

first and formost.....


do the following


enable mode

config t mode


configuration-register 0x2102

ctrl z

wr mem


that will make your router actually load the running config for you, because right now you have it set to 0x2142, which is basically not loading the running configuration from your startup config.

[phoneguy2286]

thanks...getting closer...still no DNS...unable to ping outside the LAN.

 

[DallasBPF]

Do you have the ISP's DNS ip addresses?

ip name-server x.x.x.x


(x's being ip address for your ISP's DNS address)

Curious though, why would you not want to do any NAT'ing?

[phoneguy2286]

I guess I can pull the ISP's DNS from the existing dlink router, or a connected PC.

Is there a way to make it populate automatically?

I guess I'm a little unclear on NAT.

The ISP is providing a DHCP ip address, and I have no reason to use NAT that I am aware of...

very very simple setup.

thanks for the help!

 

[Alterac]

use the import all feature of the dhcp scope so that it will automaticaly assing the dns address from the isp.

You will need to do a nat in order to provide internet on the inside, unless you have a public ip for every computer.

dhcp fix:

ip dhcp pool home
import all
network 10.10.10.0 255.255.255.0
default-router 10.10.10.1
lease 7

Can you post your updated config?

 

[phoneguy2286]

I will post as soon as I get home.

Thanks!

I am trying to learn. Any "generic" NAT setup?

thanks again.

[burtsbees]

If the dsl modem is not in bridge mode, then it is doing the natting, as well as pppoe/pppoa authentication and negotiation.

Below is just an example I found in the Ciscopedia;

The following example translates between inside hosts addressed from either the 192.168.1.0 or 192.168.2.0 networks to the globally unique 171.69.233.208/28 network:

ip nat pool net-208 171.69.233.208 171.69.233.223 prefix-length 28
ip nat inside source list 1 pool net-208
!
interface fastethernet 0/0
ip address 171.69.232.182 255.255.255.240
ip nat outside
!
interface fastethernet 0/1
ip address 192.168.1.94 255.255.255.0
ip nat inside
!
access-list 1 permit 192.168.1.0 0.0.0.255
access-list 1 permit 192.168.2.0 0.0.0.255

[Alterac]

That example is a little, overcomplicated for his setup.
I would suggest this:


interface Ethernet0
ip address 10.10.10.1 255.255.255.0
ip nat inside
!
interface Ethernet1
ip address dhcp
ip nat outside
duplex auto
!

ip nat inside source list 1 interface Ethernet1 overload

access-list 1 permit 10.10.10.0 0.0.0.255


----------------------------------
Bill

 

[burtsbees]

That is ONLY if his modem is in bridge mode! The fact that he set a private IP on the outgoing interface tells me that his modem may be NATting!

Burt

 

[phoneguy2286]

and if the modem is NATting, do I still need to initiate the Ciscopedia example?

 

[burtsbees]

No. But if it is not, let us know. The easiest way to tell is interface Ethernet1
ip address dhcp
ip nat outside
duplex half

That way you can see what IP address the modem assigns, by
sh int e1
and we'll go from there.

Burt

 

[Alterac]

Burtsbees:

Ethernet1 is the outside interface in this example, it is set to dhcp, which does not have a private ip. (I have not seen it set to any private ip's)

Ethernet0 is internal, Ethernet1 is WAN. It is a little backwards to how most set it up, and threw me for a loop also.

Then again, once he lets us know the IP he gets assigned via dhcp, my point is moot

----------------------------------
Bill

 

[Alterac]

and as I re-read all the posts, I read dlink router.. So maybe it will be an internal ip. (then again, if its a different class/range we can do 2 nats. lol)

----------------------------------
Bill

 

[phoneguy2286]

The dlink is not in the picture.. I just used it for a reference, and use it to get online while working on this little thing.

The modem is a Zytel DSL modem..shows to be using NAT (SUA Only)

assigns DHCP via the LAN interface..

also, I can plug the PC directly into the modem, and it pops right up.

I'm making progress. thanks.

The following is what I tinkered with last evening and how the router is currently configured.. I had to make some changes to the dhcp pool and created two other pools when doing so... how can I remove them from the config?
