Hi, We have been allocated 2 more IPs by our ISP for a period of 1 month for our purpose. Now these 2 IPs will be assigned to 2 Windows machines which are to be accessed from outside. We want port 21 or one machine to be accessed from outside and port 80 and 9001, 25 of other machine. Which is the best way to allow access to these machines from outside still having them under my firewall? I thought of having ip aliases on the Linux box and forwarding the connections to the respective windows box. Can someone explain an easy way for this? With warm regards, -Payal
