I am a bit new to cisco routers but not to routers in general (i used to work with zyxel, fortigate and dlink). My question is about an Cisco 857 which i manage by SDM 2.4 interface.
It is about firewall. In tab "aplication security", i see that i can block MSN. But if i check this box, it will block every pcs on the lan to access MSN !!
And guess what ? This is not what i want: I just want 3 pcs (i have their ip adress) to access MSN and block the others pcs on the lan.
How can i do that ?
ps: remain my router is cisco 857 !
