      I need to setup a site-to-site VPN endpoint that will terminate at a location, and then be able to use that location's internet connection. The configuration I have today is

      site a - LAN 192.168.10.0/24, WAN X.X.X.X
      site b - LAN 192.168.20.0/24, WAN Y.Y.Y.Y

      today site a routes all it's traffic to site b, and it get's NAT'd out on that side, this works.

      Now the new setup

      site c (Azure) - WAN Z.Z.Z.Z

      I tried to setup the same in Azure, but when you setup the VM following the instructions, there's only a single NIC, and it won't NAT the traffic from site a even if I go in and create a NAT rule (it just sends it out untouched).

      What I'm curious is if this is possible, or if I have to have a second interface (LAN) like I do currently at site b to make this work.
