Trouble port forwarding SSH
I have an Ubuntu Server 12.04 box at home that I'm trying to access via PuTTy at work, but I can't get it to connect (it just times out). I've made my home system IP static, and I set set up port forwarding in my router settings for SSH (in port 22, out port 22, forward to my home machine IP address, TCP and UDP, checked "enabled"). And there's no proxy at home or at work to worry about.
Any idea what's wrong?
(Side note: I intend to change from port 22 to something else once I get this working, but for the sake of simplicity, I left it at 22 for now.)
