  • There definitely is address transalation or (http) proxy going on. I don't want to go down the path of having the ISP bend to my request, instead, I think I should explore how to make (Debian)/etc/network/interfaces emulate Windows' NIC configuration.. ugh, worst case I might have to change server to Windows just to make this bug go away.

  • If it really is your ISP forcing http through a proxy, then it would be the same for Linux and Windows. I guess you need to investigate a bit more. Try https and try with http again, but use wget tool both on Linux and on windows. If you have access to a web server log (on an external server) - use it to check again. Your eth1 config is fine. how are the other interfaces configured? eth0? What does ifconfig say on the linux box? Commented Mar 29, 2014 at 8:15

  • Yes, I tried https and http, same results 123.123.123.120 reports 23.23.23.45. Though I had another Linux machine connect with 123.123.123.120 and ip check reported 123.123.123.120 back. So this is not a problem with Linux. Since the only difference between Linux#1 machine and Linux#2 machine is motherboard and installation of Virtualbox. I hardly think Virtualbox would cause something like this so probably the motherboard is causing this issue on a hardware level? Commented Mar 29, 2014 at 11:53
  • What happens if you use "123.123.123.121" or "123.123.123.125" on the Linux box? Did you try using wget? Perhaps your browser is being (automatically) configured to use a proxy. Check with tcpdump on the Linux box: does your web browser talk to the destination web server directly? Commented Mar 29, 2014 at 14:04
