Can't loop back into my network

I suggest you draw a diagram showing how these two networks are physically connected, also provide a little more detail on your ip addressing - I don't have a problem with your obscuring the public ip addresses, but at least specify the private (even if you use a, b & c to indicate octets that remain unchanged. It's unclear if the Actiontec is your sole link to the outside world (I don't see how it could be, but your post doesn't detail another connection, or if it does, I missed it). I can't tell you if the Netgear's WAN address is 172.x.x.201 or that's the LAN address, and for that matter if 172.x.x.201 & 172.x.x.200 are on the same network - what does the x represent (other than an unknown), and what's the subnet mask? IF all of the 172.x.x.? hosts are on the same physical & logical networks, there is no reason why they should not see one another, if they are on different logical networks, they won't unless you create routes and have a gateway linking them. Last but not least - what Netgear router are you using? One more thing - if the Actiontec IS the sole internet link, and you can access the servers using their internal address (172.x.x.200) but not the external address (67.x.x.187), the problem is going to be the Actiontec.
