Why won't NTP synchronize?

I've been trying to get NTP (Network Time Protocol) working on my
home machine. I had it before, but I just can't get it working
since I upgraded some time ago to RH 7.3. The odd thing is that
I have 7.3 using NTP at work....
Anyway, I have servers configured in /etc/ntp.conf, and I can
start the ntpd daemon using /etc/rc.d/init.d/ntpd
Then I get this status from "ntpq -p", and it never changes, nor
does the time get updated (I've obscured the server names and IPs):
[root at treat init.d]# ntpq -p
remote refid st t when poll reach delay offset jitter
==============================================================================
*LOCAL(0) LOCAL(0) 10 l 58 64 377 0.000 0.000 0.015
server1 0.0.0.0 16 u - 128 0 0.000 0.000 4000.00
server2 0.0.0.0 16 u - 128 0 0.000 0.000 4000.00
[root at treat init.d]#
Now, I am running a firewall using ipchains, and I've trained it to log
the NTP packets it lets come in, and I see stuff like
Dec 28 13:54:05 treat kernel: Packet log: input ACCEPT eth1 PROTO=17 <server1>:123 64.166.164.49:123 L=76 S=0x00 I=43584 F=0x0000 T=48 (#10)
Dec 28 13:54:07 treat kernel: Packet log: input ACCEPT eth1 PROTO=17 <server2>:123 64.166.164.49:123 L=76 S=0x10 I=64283 F=0x0000 T=47 (#9)
So I'm getting replies from my servers. Why am I not getting a time sync?
