We encounter different result when we perform DNS nslookup with the DNS forwarding service on and off.
When the DNS Forwarding Setup turn OFF:
DNS request timed out.
timeout was 2 seconds.
When DNS forwarding turn ON:
nslookup result as follow:
**All DNS queries will be added with the local domain (xxxxx.local) and return the same IP address 188.8.131.52, including the non-existent domain.
**This does not give us problem when browsing Internet, problem only during nslookup and rbl checking.
