Sorry, I must not have been paying attention. With no nameserver at
all, reverse dns lookups will fail, but most telnet and ftp clients
will connect anyway. The best way to troubleshoot this is to listen on
the incoming interface with "tcpdump". Use "tcpdump -s 155 xx0" to 
decode dns and reverse-dns requests, to see if that's even the problems.
