CISCO DNS forward

Ali kdo ve zakaj mi CISCO zavrača DNS poizvedbe, za katere bi rad da jih forwardira:

$ nslookup www.google.com. 192.168.1.1
Server:         192.168.1.1
Address:        192.168.1.1#53

** server can't find www.google.com: REFUSED

Na cisco-tu je nastavljeno (po vodiču: http://www.nil.com/ipcorner/RouterDNS ):

ip domain lookup (že po defaultu na on)
ip dns server
ip name-server (trije zunanji dnsi)

Če grem na router in dam ping www.slo-tech.com ga bo resolvalo in pingalo. Nato bo CISCO tudi vrnil rezultat:

$ nslookup www.slo-tech.com. 192.168.1.1
Server:         192.168.1.1
Address:        192.168.1.1#53

Non-authoritative answer:
Name:   www.slo-tech.com
Address: 193.164.138.20

se pravi vrača samo cached rezultate ki so vidni v 'show hosts'. CISCO je 892, Version 12.4(22r)YB3
