cisco router 2651XM
My above router is fitted with a wic-adsl card that connects to the internet.
My router has two ethernet ports. One (F0/0) is configured on 172.16.1.x and the other (F0/1) is on 192.168.1.x and both ports connect to the internet okay.
Using the wizard in SDM 2.5 I set up a low level firewall, but I want to isolate the two subnets from each other, so that neither one can see the other but I don't want to disrupt the connections to the internet. Does anybody know what commands I could use to do this? attached is my running config. Thanks for any help.
