how to configure cisco 2801

does it have any extra modules, what interface you need to configure with this ip?
post the running configuration, i'll modify it and post it back

its new i have connect the console cable to the serial port how can i connect to tit

Plug the blue cable into your PC's com port and the other end into the console port of the router.  Open hyper terminal using  these settings 9600,N,1 then hit enter a couple of times and you should connect.

Once you've connected to the router, power cycle the router.  When it reboots it will take you into setup mode.  Once you've done that we can help you config the rest.  

when you say power cycle the router?

i am on the command line now, how can i check what is the ip address of this router right now.

thanks

if you're at a # prompt, type:
sho conf

If an interface is configured you'll see something like:
interface FastEthernet0/0
 ip address aaa.bbb.ccc.ddd xxx.xxx.xxx.xxx

By power cycle I mean, turn off the power then turn it back on.

okay i have run the comand and it came up with

INVALID INPUT DELETE AT '^' maarkar

i will power down now

just rebooted its load stuff

Did you get a prompt asking if you want to go into setup mode?

sorry forgot to tell that when i restarted it took me to the command prompt LTSCISCOSDSL>

no i go directly to the command prompt

is there any command which i can use to see what is the current IP address like in windowns you have ipconfig

type en at the > prompt, this should give you an enable prompt #, then type sho conf

here's a good "hoe to" on basic router config:

http://www.evonetworks.com/website_g4/support/supportdocuments/manuals/b_cli.pdf

thanks for this but i can not change the ip address as it say invalid on marked

i tried

enable
configure terminal
ip address 192.168.10.1 255.255.255.0
and on this command it says
invalid at marked ^ and the mark is on p

what to do

Assuming interface fa0/0:

routername>en
routername#conf t
routername(config)#int fa0/0
routername(config-if)#ip address 192.168.10.1 255.255.255.0

then do a control-Z to exit config mode
routername#wr mem

okay i have done it but i can not ping 192.168.10.1
what to do now

i cant even telnet as i am connected thorugh the blue cable do i have to connect through ethernet cable?

one more thing when i do ip on prompt it comes up with

translating "ip" domain server (255.255.255.255) why is that as were i have 255.255.255.0

okay i have connected a laptop to the router and i can access the router through web but its not going in i mean loggin in as i am using the same password which i used to connect through blue cable

okay i have done it but when i connect it through http://192.168.10.1 it ask me fr passord and login when i use the one i try to connect to terminal service it doesn allow me in

is there anyother passowrd?

the default password is cisco

got that now
how can i set up NAT TABLES and Access list to the mail shot server whose ip address is 192.168.10.226

how can i open port 25 in the router

do a #sho conf and copy it here.

Can you give us a block diagram of your network and where this router will be?
I'm not sure why you would need NAT.

Network is


CISCO ROUTER

LINUX BOX (RUNNING MAIL SERVER)
WORK STATION DIRRCTLY CONNECTED TO THE ROUTER (192.168.10.226)

i need smtp port open on this workstation
i need telnet port for thei s workstation also

Like this?

192.168.10.20

   WS-----Router-----Linux Box (192.168.10.226)
              |
    192.168.10.1

yeah

192.168.10.220 ---->- relay email on 192.168.10.226 -------> send out through ------>192.,168.10.1 router

This is the way I read your last post, I apologize for not understanding but could you rephrase your request?

thats fine 2PiFL,

so workstaion send emails to Linux box and then linux box send it out to clients through router.

hope this explain but right now no email is going out of Linux box

amma, let me see if I understand.  You want someone on the other side of the router to be able to specify 192.168.10.1 as their mail server and have the mail deliverd to 192.168.10.226 instead?  That someone being either a user with a mailbox on .226, or some other server attempting deliver to .226?  

BTW, what is on the other side of the router?  An ISP?  Another site?  Corporate network?  I am asking because I am trying to understand exactly what we need to translating into what, if that makes any sense :)
