Is it possible to configure a server such that one can ssh into that server internally on a LAN while being able to ssh into the network interface that communicates on the WAN out to the Internet? How do we handle this? Do we just open port 22 for ssh for both LAN and WAN and call it a day? Is this going to pose a security risk by allowing port 22 traffic from the WAN internally to our LAN? Can we even do this? The answer to this question is, YES! How can we take care of this without posing an unnecessary risk on our server? The answer to this second question is simple.
