Good evening.
I just got a Cisco 2811 router and is trying to use it as a plain router for now. (Such as linksys)
Since my ISP is giving me address by DHCP.
I'm trying to connect FastEthernet0/0 by dhcp to the ISP
and setup NAT and DHCP on FastEthernet0/1 to give internet connections to each clients in LAN.
I think the DHCP setup was done and running.
But the NAT and ip routing seems to be some trouble.
I can't get clients in the LAN to connect to the internet.
P.S: The connection from the ISP comes out as RJ-45 Ethernetcable with DHCP.
So if it were other routers, I just plug it in and the setup would be done.
Here's my setup:

With regeards,
Thank you for your help in advance
