<div dir="ltr">Hi Folks,<div><br></div><div>Working with a B2B partner who has exposed non-RFC1918 addresses 172.31.1.2 and 172.31.1.3 through a VPN tunnel to our environment, and this works fine for hitting a web service down the tunnel from our local networks. We have a development footprint in AWS that is shanking at this, because an overlying abstraction layer for how AWS S3 instances route means that if it sees a non-RFC1918 range it sends it out to the Internet regardless of any host or other level routes that are specified. I can set route add <a href="http://172.31.1.0/24">172.31.1.0/24</a> via a gateway or for that matter the loopback until I go blue in the face and the server will merrily continue to try and find the IP on the Internet.</div>
<div><br></div><div>What I need to do, other than not allow design decisions that involve non RFC-1918 addresses for private networks, is redirect a TCP port (443) from an IP that I *CAN* hit inside our network, to the 172.31.1.0 range down the tunnel, so that <span style="color:rgb(0,0,0);font-family:Arial,Helvetica,sans-serif;font-size:12px;line-height:18px"><a href="http://1654287.r.msn.com">1654287.r.msn.com</a> stops scratching his head at the traffic trying to hit him from AWS.</span></div>

Netcat? And before anyone says NAT, there's already been enough bad decisions made here.</span></div>
