[7.403]Reverse-dns doesn't work

wingman
I am unable to use nslookup. It seems that reverse dns doesn't work at all. I've searched both the kb and old threads and I think I need to define something on the request routing tab. I have no issue "talking" to the devices within the network. 
I don't have an internal DNS server.(reverse-dns issue is not related to the current firmware version)
Could you please advice on how to proceed?

    (Oops - I just noticed the following doesn't apply because you don't have an internal DNS server.)

    BarryG recently taught many of us this trick.  You're right that it goes in 'Request Routing'.

    So, for example, if your internal network is 172.16.1.0/24, define:

    1.16.172.in-addr.arpa → 


    Cheers - Bob
    PS I don't know how to do reverse DNS with the Astaro DNS Proxy.

    Indeed I don;t have an internal dns

    When trying to use nslookup
    server: Unknown
    address: 192.168.2.100 (astaro address)

    and I am unable to resolve any client

    I've also tried adding static entries for the client

    i.e  client A--> 172.16.1.2 with no luck [:(]

    Yeah, it's not really meant to be a fully-functional DNS server with backward lookup zones and all.  You might suggest that in feature requests.

    Cheers - Bob

    You _might_ be able to put reverse entries as static DNS definitions... be sure to use the proper format, e.g.
    1.0.0.10.in-addr.arpa

    I've tried that as well but the ip address field accepts only ips and not letters (1.0.0.10.in-addr.arpa)

    Could you please vote the reverse dns feaute as users that don;t have an internal dns don't have any reverse-dns capabilities
