BIGIP DNS forwarder
Hello Everyone,
I need small help with dns forwarding on F5 DNS.
At present we have wide ips configured on F5 dns like example: test.abc.com; uat.abc.com etc
Under the zonerunner section it automatically has created the zone for "abc.com", so far so good.
We have a bind linux server which has got some dns A records in the same zone like test123.abc.com etc.
Now I want F5 DNS to reply the queries for the all the wide ips configured on F5 DNS and simply forward all the request which are not configured on f5 dns to bind. For this I have configured the forwarder and allowed recursion in the named configuration. When I did the nslookup pointing dns queries to listener on F5 dns for test123.abc.com I found that F5 is getting the request but not forwarding it to bind.In a nutshell I found that f5 dns wont forward anything to bind on zone "abc.com" becuase if I try dns query for another domain like it forwards the request to bind, and I think the reason becuase F5 has some wide ips in the zone abc.com it considers itself as master of that zone atleast this is what I see under the zonerunner configuration.
I tried to create the forwarding dns using a wildcard like *.abc.com, but f5 wont let me do that.
We have a cisco GSS at one of the site which exctly does the same thing, and forwards the request for a wildcard domain *.abc.com to binds.
Can anyone suggest how can I do this on F5, any suggestions would be appricated.
Thanks, Pankaj
