I'm still fairly new to ACLs, but here's what i need to do... i've got multiple networks, on the 255.255.255.224 subnet, and i'm trying to set it so that Computer A cannot telnet Router A, but can still perform other functions (Ping, FTP, etc.), and that all other computers and routers can still ping the specific router.  i'm stuck, i can either make it so that no one can ping the router, or so that everyone can.

could someone help me out here?
