Another strange dns question (and I have RTFM)

[Nick Brooks]

I'm in the process of upgrading my server at home and have migrated from 
RH 7 to Fedora Core 3.

My machines are:-	

aquanta.sixandseven.net 192.168.1.100 (FC3) (new)
server.sixandseven.net 192.168.1.100  (RH7) (old)

The old machine (server) was working fine: ie

     # dig @192.168.1.1 demon.net

gives the expected reply

 From my new server

     # dig demon.net
     # dig @localhost demon.net
     # dig @aquanta demon.net

all give the same (correct) response BUT

     # dig @192.168.1.100 demon.net

gives

	; <<>> DiG 9.2.4 <<>> @192.168.1.100 demon.net
	;; global options:  printcmd
	;; connection timed out; no servers could be reached


The only difference I can see is that the log files show a slight 
difference when named is started:-

New machine shows:-
named[27598]: loading configuration from '/etc/named.conf'
named[27598]: listening on IPv4 interface lo, 127.0.0.1#53
named[27598]: listening on IPv4 interface eth0, 192.168.1.100#53

Old machine shows:-
named[7938]: loading configuration from '/etc/named.conf'
named[7938]: listening on IPv4 interface lo, 127.0.0.1#53
named[7938]: listening on IPv4 interface eth0, 192.168.1.1#53


Any suggestions as to where to look for the problem gratefully received.
