Cisco Setup

New to Cisco, need some help. I have a 2801 I'm trying to use to router (forget the WIC). I am trying to use FA0/0 and FA0/1 only.

I have computers on one side of the router (FA0/0) that use the 172.18.6.50-100 (255.255.255.0 sub).

I have a DSL pipe on the other that has 5 IP's available with a gateway of 75.190.82.66.

I would like the 172.x computers to be able to browse the internet, so far, no luck. I need just a basic setup.

I have configured the FA0/0 to 172.18.6.3 and the clients to point to that as their gateway.

I have configured the FA0/1 with an IP of 75.190.82.68 255.255.248.0.

I tried a default route ip route 0.0.0.0   0.0.0.0   75.190.82.66. I don't no what else to set. I have tried typing dif routes, setting access-list, different things.. essentially tried to copy from examples on the web to no avail. Anybody might help with this config?.

Thanks a bunch,

BUC

Re: Cisco Setup

Hello,

Please try the following:

Access-list 1 permit 172.18.6.0 0.0.0.255

ip nat inside source list 1 interface fa 0/1 overload

This should allow you the basic internet connectivity. If you would like to

use the remaining public IP addresses for any specific servers on the

inside, you can do that using the following format:

ip nat source static extendable

Hope this helps.

Regards,

NT
