Next one is address range for multicast transfer leave the default value and select ok[thumb:2:c:l=p]
now you can see the screen for ttl for multicast address leave the default value and press enter[thumb:3:c:l=p]
Now it will ask for base directory by default it will be /tftpboot directory you need to create with 777 permissions[thumb:4:c:l=p]
Change mode of the directory
#chmod 777 tftpboot
Security configuration for atftp
