Re: If everything's encrypted, what's the problem?
This.
Even in my own little home network, all traffic (except for the open WiFi I run, but it's on an isolated subnet) is encrypted, even when it's not leaving my LAN. I don't do this because I don't trust my router, I do it as a layer in my multilayered security: it's yet another roadblock should an attacker gain access to my network.
