Michael, Glynn,
Thanks for your replies. Once I read Glynn's reply, it suddenly became
obvious ( amazing thing, this hindsight!) to me that the 'Can't find server
name for address 192.168.0.2' meant that it could resolve to ip-address to a
name. So I went ahead and defined the reverse-DNS lookup, and voila! things
started working.
The 'forwarder' configuration that you suggested is next in my to-do list.
However, I do not have to type 'server 192.168.0.2' (you said ....1 not ....2
- am I misunderstanding something, or did you make a mistake?) in order for
nslookup to work. 'nslookup' without any arguments works fine for me.
