Hi,
I have a strange problem using the dns forwarder proxy: PTR record lookups don't work for the network behind the firewall while there is no problem for lookups of any other ip-adresses, and if I specify the DNS server that's used for forwarding the same PTR records are resolved without problem.
Example, not my own ip-addresses:
firewall: 101.102.103.1
primary dns: 101.102.104.105
PTR records 101.102.103.2 - 101.102.103.30 are NOT correctly resolved by the astaro dns forwarder proxy running on the firewall.
The result: No hostname information is available for "101.102.103.2"
101.102.103.1 itself works fine and any other ip-addresses I tried work as well.
If I do not use the proxy for dns lookups but the primary dns 101.102.104.105 the hostname is correctly returned for 101.102.103.2 - 30.
The same happens for lookups from both sides of the firewall, and only PTR lookups of the "protected" subnet don't work (from both sides).
Is it a known problem and/or can it be reproduced elsewhere? (ASL 3.209, registered, office version)
