Is there away to make an access list to only allow telnet from the serial interface (ex: the /30 address on that interface) or default gateway, if the ip address or gateway isn't known. I want to know this because I have about 500 routers I need to put this on and I want to tftp a standard config to each one and the default gateway is different for them.
