bind problem

[re.ivan at gmail.com]

My network is :





  Router ADSL
          |

   SWITCH |---->   MyFirewall  ----- MyServer (dns+mail+www) ---
(eth0 )192.168.0
     |                     eth0    eth1    eth1                     |

     |
   |-------  (eth2) 192.168.1
     |--   OldServer (dns+www)

MyFirewall eth0  xx.yy.zz.7
                 eth1   192.168.5.254

MyServer    eth1  192.168.5.2
                  eth0   192.168.0.254

Firewall is a debian release with iptables. In this i have activate
DNAT on port 53 from xx.yy.zz.7 to 192.168.5.2

Myserver is a fedora 5 with bind9

OldServer is a rh 7 with bind

Test:

 dig  miodominio.it  axfr  --> result OK


 dig  @dns3.nic.it   myfirewall.miodominio.it


result:
; <<>> DiG 9.3.2 <<>> @dns3.nic.it myfirewall.miodominio.it
