[Pdns-users] Recursor not working

I've having difficulty with connection timeouts with the recursor on my
newest install of PDNS. I have two PDNS (v2.9.16) servers running on RHEL 4
(32 bit) with a recursor option without a problem. The new box is running
PDNS (2.9.20) on Suse v10 64 bit. I'm using a MySQL backend.
Querying any local address works fine. Remote addresses cause a timeout.
I've added the recursor line to my pdns.conf file as follows:
recursor=220.127.116.11 (one of my ISPs DNS servers)
I've tried omitting the allow-recursion line (as I have with the two working
boxes) and also have tried it set to 0.0.0.0/0. No difference.
At a prompt on the server a query such as dig @18.104.22.168
www.google.comreturns an accurate response. However, the query dig @
192.168.2.4 www.google.com displays:
<<>> DiG 9.3.2 <<>> @192.168.2.4 www.google.com
; (1 server found)
;; global options: printcmd
;; connection timed out; no servers could be reached
The web server within PDNS shows recursing-questions as a positive number,
one which increases as I enter queries similar to the above. I see entries
such as "Recursive query for remote 192.168.2.4 with internal id 0 was not
answered by backend within timeout, reusing id". It would appear PDNS is
having difficulty connecting to my ISP's DNS, but I can do perform this
locally on the server. The connection is good.
Does anyone have any suggestions?
