Hi, I'm learning CISCO at the moment and was wondering if you can help me. My 877W Router is configured with DHCP from to and any PC which is connected to the router can get internet access. is the router.

My question is can someone tell me :

a. How I limit internet access so say only IP addresses, can get internet access and no-one else can but the other clients etc can still talk to the other PC's on the LAN.

b. How I limit internet acess by fastethernet port so say ports 1,2 and 3 can get internet access but port 4 cannot.

Running config is attached.

You have to modify access-list 1 like this:

access-list 1 permit

access-list 1 permit

This denies NAT translation for the other host which effectively denies them internet access.
