Configuring Cisco 3620 router

[amargdesai]

I am quite new and haven't worked before with Cisco router. I have a Cisco 3620 router with only one ethernet interface (FastEthernet 0/0).

I want to configure it so that the router will have ip address of 192.168.2.2 (255.255.255.0). I am not using DHCP so all the machines in the network are configured manually.

My running-config is as follows.

!

version 11.3

service timestamps debug uptime

service timestamps log uptime

no service password-encryption

!

hostname router

!

enable secret xxxx

enable password xxxx

!

!

!

controller T1 0/0

framing esf

linecode b8zs

channel-group 0 timeslots 1-24 speed 64

!

!

interface FastEthernet0/0

ip address 192.168.2.2 255.255.255.0

!

interface Serial0/0:0

no ip address

shutdown

!

ip classless

!

dialer-list 1 protocol ip permit

dialer-list 1 protocol ipx permit

!

line con 0

line aux 0

line vty 0 4

password xxxx

login

!

end

Can someone give advise on what should I use for default-gateway, default-network and route?

I want to use name-server which has class B ip address. 131.x.x.x.

If my router can route all the traffic to 131.x.x.y (gateway in the same LAN as router) then I can connect to Internet.

Can someone tell me how to do this?

Regards,

Amar.

Hi

i feel u need to have 2 ethernet interfaces in your router to have the reachability to the 131.x.x.x series from your local lan which is in 192.168.2.x series..

eventually u need to deploy nat to have this kinda access in place...

if you got to have that you can configure one of your interface on 131.x.x.x series and configure it as a nat outside interface and keep faeth0/0 as ur inside interface.

you need to configure up a access list and also the necessary overloading to achieve the connectivity.

i think this link will def help u out to find more details about the scenario and config details about which i m mentionining over here..

And again you can have the ip reachability using normal static ip route in your box..pointing to the ip which can be used to go out to the public/outside world..
