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
