Question for networking pros

[§ôµÏG®ïñD]

How can i change the default ip (192.168.0.1) to something else in the ICS settings.  My adsl modem has its own ip which is teh same. So i\'m getting conflicts whenever i try to enable ICS.  I don\'t want to use a router either.

Change the modems internal ip to somthing else. say 1.1 Then enable ICS. ICS is a cheap and dirty gateway and dhcp server. Which means there is not much you can change about it.

can\'t you configure your network access to dynamic IP?

The modems typically keep an internal ip so that you can get into it if need be. If it had a pub ip then one account would yank two ip\'s in a world that is strained for ip\'s already.

I sort of figured that with two nics there would be no issue, but apparently there is. So change the modem internal ip.

With 2 nics, you still can\'t add ICS, we tried. The modem uses the SAME ip ICS uses. It automatically choices 192.168.0.1  but sence the modem uses that ip, it conflicts.  Dynamic IPs, or Static Ips won\'t change anything. The modem has its own ip, and ICS uses the same.  M$ could have allowed people to choice their ICS ip.. knobs.  

You can\'t change the modems ip. The modem has a password that disallows it.  We tried with

$ telnet 192.168.0.1

> ip
> route flush
> route add default 0.0.0.0 10.0.0.254 00:00:00:00 1 0 1
> subnet flush
> subnet add ethernet.home ethernet 10.0.0.0 ff:00:00:00
> enable ethernet mtu 1500 10.0.0.128

At this point the telnet connection will hang up, because the modem IP address has changed. Nevertheless, do not kill the telnet client: let it time out... It is really important, otherwise you will not ever be able to reconnect to the modem, and your last option will be its hardware reset with the small button behind.

Once timed out, you have to change your client machine network interface config.

Instead of something like this, in /etc/network/interfaces:

iface eth1 inet static
address 192.168.0.2
netmask 255.255.255.0
broadcast 192.168.0.255
network 192.168.0.0

Put something like that:

iface eth1 inet static
address 10.0.0.1
netmask 255.0.0.0
broadcast 10.255.255.255
network 10.0.0.0

Then, execute:

# ifdown eth1
# ifup eth1

Now, you will be able to connect onto the modem via:

$ telnet 10.0.0.128

Save changes into the flash with:

> config save

But it asks for a password before you can do anything. We\'ve tried Admin and Orion99 which were meant to be some passwords that dlink use for the type of modem we have (DSL300+)

We did have a DHCP server linking into a switch then to 2 comps. But the server hds are F#@ked. So i guess we\'ll have to get a new one.  

Thanks anyway.


ps. Whats worse is you used to be able to alter the ICS ip with regedit.  Seems you can\'t anymore.

screw ics
 
honestly, it\'s more trouble than its worth

well i emailed dlink and the response i got.

Hi there,
Thanks for writing to us.
Usuallly you cannot change the default IP address on the modem, but please try
the following
which may work.
In order to get access to modem\'s command line interface you can use Telnet.
In Windows click on Start > Run... and type telnet 192.168.0.1 (where
192.168.0.1 is modem\'s IP address. DSL-300 has 192.168.1.1 address).
Click on OK. You will be prompted to enter password. Default password is
"private".
Then enter the below commands:

To change IP on DSL-300+ from 192.168.0.1 to 192.168.0.10:

192.168.0.1> ip device delete ethernet

??:??:??:??:??:??> ip device add ethernet ether //bridge mtu 1500 192.168.0.10
OR
??:??:??:??:??:??> ip device add ethernet ether //bridge 192.168.0.10

192.168.1.1> ip device list     (to double check the IP (both above will give
MTU=1500)
192.168.1.1> config save    (to the save the settings)
192.168.1.1> restart

Hello,

How can i change the default IP in the dsl300+ adsl modem.  It conflicts with
Microsoft\'s ICS IP.

Any help would be great.

Nathan.

So i\'ll try it out later, I\'m thinking i\'ll most likely get a lost connection reply once i delete the ip..   Guess i\'ll find out soon enough.

WoooHooooo   Finally got it working.

This is how I fixed this problem.
I\'ve got a 300 buck router for free.   It\'s a Road Lanner  BRL-07P (brothers mate gave it to us)

At first I was having shit loads of problems because i forgot to delete the account that the ADSL modem stores.  It stores my connection details etc (Via PPPoE).   So once i delete that account on the modem, and setup my router to do it instead.  Wella.  4+ Pcs sharing the internet on a stupid modem that has the same ip as ICS.   (both cannot be changed either)

My brother and i took ages trying to setup the DHCP server.
To find it wouldn\'t work either.  Couldn\'t figure out why though.
I worked on that stupid thing for hours.  
But now I’ve gotten this router to work all is good.   (Brother hates it when i do shit he\'s qualified for)    man he won\'t live this down hehehe.

Had problems with the old router. So i got a new one. a Dlink DI-704p. It supports upnp, which the other didn\'t. It also supports everything i need it to. Port forwarding etc.. the other had major problems with port forwarding, even dmz mode wouldn\'t work.. Stupid router "kicks router"
