Hello,

following problem:

I have a network 172.17.180.64/255.255.255.192 (LOC). Default Gateway 
172.17.180.67
The Shorewall Firewall is Defaultgateway and has IP 172.17.180.67.

Behind a OTHER CISCO Gateway 172.17.180.68 is a DMZ which uses the 
Subnet 10.100.100.0/255.255.255.0
In this DMZ is a DNS Server with IP 10.100.100.11

The Problem:
On all Clients in the 172.17.180.64/255.255.255.192 net the OLD DNS 
Server (10.10.10.11 !!!) is written in the Network Settings,
and the CISCO Accepts only Packets to the 10.100.100.x subnet.

The only thing i want is to FORWARD all UDP/TCP 53 connects to 
10.10.10.11 to the new DNS 10.100.100.11 !!!

I already used the follwing RULE on 172.17.180.67:
DNAT      loc     loc:10.100.100.11               udp     53   -   
10.10.10.11
DNAT      loc     loc:10.100.100.11               tcp     53   -   
10.10.10.11

but this doesnt work.

Please Help !!
