It will not however explain why one of the boxes does not get a public IP (the problem outlined in the OP's original message in this thread) but the other one does. But I agree that the ifconfig/ipconfig output would be very beneficial and by far the easiest info to get to the list to help us help him. I'm less clear on why you'd be looking at open ports as it relates to his problem of both machines not getting a public IP. The testing I suggested wouldn't be difficult to do and would also help quite a bit. Here is a bit more detailed set of steps I suggest the OP tries. 1 - boot the Windows machine only (Linux machine off). What is the output of the ipconfig command? Is the Internet connection working properly? 2 - boot the Linux machine only (Windows machine off). What is the output of the ifconfig command? Is the Internet connection working properly? 3 - boot the Windows machine first followed by the Linux machine. What is the output of the ipconfig and ifconfig on the respective machines? Is the Internet connection working properly on both machines? If not which one isn't working properly? Can the machines ping each other? Can they ping the gateway? 4 - repeate step 3 but boot the Linux machine first then the Windows machine and provide answers to the same questions. Step 1 & 2 assertains that both machines work fine on their own. Step 3 & 4 attempts to determine if the first machine connecting works well but not the second machine (which would suggest only one public IP is being provided by the DHCPserver and certainly the ip/ifconfig commands would verify if that is the case or not). And certainly confirmation with the ISP on allocation of static IPs would eliminate a potential source of the problem that cannot be corrected by the OP (work arounds are possible of course, but he would not be able to get two public IPs regardless what troubleshooting suggestions were implemented) I'll refrain from further postings and await further updates from the OP as I've exhausted all the options I can suggest in absence of further details from the OP. I think many of us agree on the potential troubleshooting steps. Which order they are undertaken is not important so long as they are undertaken and the results shared with the list so we can ascertain if the problem has been identified or if further advice is required Jacques
