Applying ACL to the TFTP process

How do I apply an ACL to restrict TFTP communication to an IP address.

TFTP uses UDP port 69. Just build an ACL to permit or deny access to this port, apply the ACL inbound otr outbound on an interface and that should do it for you.

Re: Applying ACL to the TFTP process

Thanks. I really don't want to apply this to an interface on the router but to the TFTP service. I know that for NTP one could use the "ntp access-group peer" command to apply an access-list to the NTP service. Is there a similar way of doing this for TFTP?
