Hello,
Still trying to get DNS on a Cisco 2900 router to work.
Interesting part is that when I do reverse lookups, I get an immediate answer.
# nslookup 192.168.23.2 192.168.2.37
2.23.168.192.in-addr.arpa name = mytestpc.
Authoritative answers can be found from:
So it seems that I might be missing something.
I did set "ip domain name localdomain" I don't know if that is an issue?

well, as a server, so it can resolve local addresses and forward requests that are not local.

it is working for now, I just "hard coded" the ISP's name-servers in the router's dns

Oh thats great thanks for the update.

well, what I would wanr ideally, is that since the WAN interface gets the name servers automatically, the dns service can use them too.
But yes it looks like it is starting to work

Yup,
the DNS part works, one thing I would like to improve is that when the "outgoing connection" with the ISP is down, the DNS server would not time ot, or time out faster. Because it seems that even for local lookups the dns server still wants to talk to a "domain server" first?

it's not a real big deal, when it happens it is annoying.
The DNS part is working, the stubborn issue I have now is with DHCP, different thread.
thanks!
