I am trying to provide Windows 10 with router capabilities(IP Forward). Yes I know I could buy a router or switch. This setup is for TESTING only.

Found a good resource: http://www.home-network-help.com/ip-forwarding.html

However after setting everything up, I still cannot get to the internet from LAN2(USB). LAN1 can get to internet. My setup:

  • Computer 1

    • Lan1 (main connection, can access Internet)

    • Lan2 (USB NIC)

      Gateway -
  • Computer 2

    • Lan1 (Connected to Lan2 of Computer1)


In regedit I have enabled IPEnableRouter. I rebooted my computer.

  • I can ping Lan1-Computer2 from Lan2-Computer 1
  • I can ping Lan2-Computer1 from Lan2-Computer2
  • I can ping LAN1-Computer1

So LAN1 can contact LAN2 vice versa but not the internet (which gateway is

Any help please?

  • Out of curiosity.. why not simply use the Windows 10 Internet Connection sharing? (Control Panel - Network and Internet - Network Connections - right click and Properties on the network you wanted to share - and go into the sharing tab) – Darius Apr 14 '17 at 22:43
  • Because that is the obvious answer. Again just testing other options. – Benjamin Jones Apr 15 '17 at 17:26

On Computer 1 make sure the Routing and Remote Access service is enabled and started. In windows 10 it is disabled by default.

  • OP preferred static routing enabled by IPEnableRouter over ICS. NAT through RRAS is only available for Windows Server. – guest-vm Feb 26 '18 at 8:33
