I'm using a new Cnet CAR-854 router, and for some reason, it seems to return DNS information on port 20458, instead of 53:

dig ns1.xnet.co.nz
;; reply from unexpected source: 192.168.1.1#2048, expected 192.168.1.1#53

; <<>> DiG 9.4.1-P1 <<>> ns1.xnet.co.nz
;; global options:  printcmd
;; Got answer:

;; WHEN: Sat Feb 23 23:08:35 2008
;; MSG SIZE  rcvd: 48



As a result of this, to retrieve the IP address for a website takes around 5 seconds, unless the DNS info is already cached! This is absolutely rediculous. Yes, I can specify the DNS server myself for each machine on the network, but I shouldn't have to do that- the router should be able to handle things fine.

Does anyone have any ideas about what I should be looking for in the configuration of the router to fix this? Thanks.
