Cisco Router Setup 1841

[khansen011]

Hey everyone!

I need some help, i am new to using Cisco routers (as far as setting them up my self) so forgive me if this is something simple that i am over looking/not understanding.

I have a cable internet from cox.

They gave the the ip address below....

IP: 98.191.**.147 

DG: 98.191.**.129

SNM 255.255.255.224

the ip address is the ip address that will connect the router to there modem. 

On the lan side i have the following

Ip address 10.0.4.1

DG 10.0.4.254

SNM 255.255.255.0

What i need to do is take 10.0.4 network and tell it the inter net is at  the 90.191 network address and connect to the internet that way.  

i have been watching some youtube videos on how to do this but there is something im missing and i cant figure it out.

If some one could help me shed some light on this i would greatly appreciate the help!!!!

as of right now i get no internet connection on the 10 dot network.

Hi 

In order to give access to Internet to your lan network, you need to do natting and add the default route

Below the config 

Interface f0/0

Ip nat inside

 !

Interface f0/1

Ip nat outside 

 !

Ip access-list extended NAT

Permit ip 10.0.4.0 0.0.0.255 any

!

ip nat inside source list NAT interface f0/1 overload

 !

Ip route 0.0.0.0 0.0.0.0 98.191.**.129

how this is clear.

PS: don't forget to rate and mark as correct answer if this solved your issue

i can ping 98.191.**.147 and get a 100% success but i try to ping 10.0.4.55 (the other pc) i get a 100% fail.

In other words i get single directional traffic

On your acl for nat you need to deny traffic from your lan network to your lan network. It had to be the first statement before the permit statement
