configure linux for isocated IP.
I am having Redhat Enterprise Linux with two network Card, I have configured this linux as a router.
First network card connecting to my company public network port (146.223.xx.xx) and another connecting to windows 200 server.
This windows 2000 server doesn’t have any other network card. Only one network card which will get network cable via this linux machine.
My aim is whenever somebody will access this windows server it should go via this linux machine (which is secure),I had configured below files in linux machine.
/etc/dhcpd.conf
/etc/shorewall
/etc/sysconfig/network-scripts/ifcfg-eth0
And all other require files.
All configuration has done I am able to access this windows server by remote-desktop (typing linux machine hostname).
Windows server able to get 192.xxx.xx.xx isolated IP address through linux machine. As I had configured /etc/dhcpd.conf
Problem is my windows server can not talk with my company public network (146.223.xx.xx), even I can’t ping. However I am able to do internet surfing from windows server so it mean winnows server talk outside, but can not to company public network (146.223.xx.xx).
I believe I missed somewhere a minor settings but don’t know what,
Appreciated your help here, please reply me for any help surely will assign point and full point for correct answer.

Re: configure linux for isocated IP.
If someone from your public network wants to go to the IP of this Windows server, then it should go via your Linux station.

Re: configure linux for isocated IP.
could you please post the following:
1. routing table of the windows server and linux router along with the IP of the Windows server.
2. The output from `iptables -l` on your linux router.

Re: configure linux for isocated IP.
First of all, stop the firewall and made the test without it. After you could enable and put some rules.
If I understand, the linux box is configure like a router, so the windows have to route to the linux IP { it seem correct because dhcp server = gateway }. After that, the linux have to route to the public network.
What about the routing table of the linux box?
Do you play with tracert on the windows, where it's stopping?
