I have not converted them yet, also because I was not sure on how I have to
do it.
Now reading the man of named I discover that I can specify the default TTL
keyword as the first line of the zone file:
$TTL nnnnnn

Fine... I'll check it too, thanks...

As you have understand I have not yet converted them yet. Btw your
observations were too much interesting.
This was the sample I sent.

This exactly the point.
The sample I sent was the DNS of an intranet connected to the Internet by a
cable modem with ppp -nat enable.
This is the output of ifconfig -a:
freebsd:/home/gmarco> ifconfig -a
ed1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255
ether 52:54:05:df:0e:46
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
inet 194.243.20.91 --> 194.243.20.2 netmask 0xffffff00

Do you think I have to run 2 DNS ?
I really don't want my boxes inside the intranet to be accessible from the
Internet (they are almost Windog 98 boxes). The DNS is needed only for the
"inside" boxes to query their requests for the Internet address.
The configuration seems to work now, do you think I have to change it ?

I have that book (indeed I have two editions of it, also the last :-)
Perhaps I have to read them better :-)
Thanks again for your attention and your kind replies.
