Hi, I have the following situation. I have my Linux box on the company network. I also have a Windows box for which I don't have a network port, so I connected it back-to-back to the Linux box via a second NIC on the latter. Now, I need to work with the company network from the Windows box. I'll list the ways I tried and the problems with each of them, and perhaps you can advise how it's possible to solve the problems using one of those ways, or maybe suggest another way altogether. First, I did simple NAT. I gave a different subnet to the small network (Linux <-> Windows), and on Linux I enabled IP forwarding, and masquerading for this subnet. I then could access the Internet from the Windows box. However, I couldn't log on to the NT domain, because broadcasts by the Windows box (needed for finding the PDC) weren't forwarded. Next I tried bridging. I bridged the two interfaces on my Linux box, and the Windows box got an address from the DHCP server like any other machine. That was perfect, but there was one problem -- I access the Windows box via VNC, and this causes all the VNC packets to go to both interfaces and flood the company network. Also, the back-to-back connection is 100 Mbit, and the company network is 10 Mbit, and I suppose that bridging them makes them both 10 Mbit. Not good. Then I tried proxy ARP. I gave the Windows box a static IP within the company network subnet and did arp -s etc. This came out the same as NAT -- I could connet to the Internet, I could even ping internal company servers, but broadcasts apparently still didn't go out. So the problem basically is that I want broadcasts from the Windows box to go on the company network, but I don't want my VNC traffic to flood it. Is it possible to achieve? Any ideas? Some sort of tunneling perhaps? Something else? -- Alex Shnitman | http://www.debian.org alexsh@hectic.net, alexsh@linux.org.il +----------------------- http://alexsh.hectic.net UIN 188956 PGP key on web page E1 F2 7B 6C A0 31 80 28 63 B8 02 BA 65 C7 8B BA An idealist is one who, on noticing that roses smell better than a cabbage, concludes that it will also make better soup. -- H.
