Hi all,
 
I am in trouble to do a rule. Anybody can help me?
 
I want to redirect all traffic from a specific valid ip and specific destination port to a machine located inside a LAN.
 
This rule is to access SQL Server that is located inside a LAN and i have a valid ip address in a linux machine with iptables.
 
I've tried the following:
 
Lan IP with SQL Server: 192.168.0.10
Valid IP with iptables: 200.221.98.123
Valid IP that will acess SQL Server. 200.206.123.112
 
This rule i've put in the machine 200.221.98.123
 
iptables -t nat -A PREROUTING -p tcp -s 200.206.123.112 --dport 1433 -j DNAT --to 192.168.0.10
 
And now i configure my SQL Server to connect to 200.221.98.123 but i still can't connect. Dou you have any idea why it is not working?
 
The ip's i've mentioned are just for example.
 
Thanks a lot
 
Rodrigo
