I have an 1812 cisco router, and I have been trying to set this thing up for about a month now.

I am using SDM to setup the router but I am unable to set it up successfully.

My enviornment:

-I have a SBC DSL Connection

-Cisco 1812 router

So far via SDM, I have configured my VLan1 to the IP My Fast Ethernet 0 or 1 is not setup yet.

Can someone help me setup my FE0 so that I may access the internet. Remember I connect to the internet using SBC DSL.

Please help

you need to use NAT on the router. use following commands

int fa0 ( interface connected to internet)

ip nat outside

int fa1

ip nat inside

ip access-group 150 in

ip nat inside source list 150 interface fa0 overload

access-list 150 permit ip any any
