On using loopbacks for tftp, syslog, NTP

Hello all,

I've been reading an older ebook called Cisco ISP Essentials and the best practice approach is to use loopbacks for all of these services.

But I can't get it to work.

By themselves all do but at soon as configured to use loopback I'll see the router trying to connect but it bombs out. I've rolled back so that only ftp is now on the loopback... what am I missing?

Hardware: 2621
IOS: 12.2(11)T

Relevant bits of Current config
version 12.2
service nagle
service timestamps debug uptime
service timestamps log datetime localtime show-timezone
hostname 2621AS
clock timezone EST -5
ip subnet-zero
ip ftp source-interface Loopback0

interface Loopback0
 ip address
interface FastEthernet0/0
 ip address
 duplex auto
 speed auto
ip classless
ip route
no ip http server
ip pim bidir-enable
logging source-interface FastEthernet0/0
exception protocol ftp
exception ****
ntp clock-period 17180650
ntp server source FastEthernet0/0 prefer
Thanks for any pointers!

    You need to have a route back to the loopback interface in the routing table. Make sure you can ping the loopback from the computer you are using as the server.
