What if your LAN machines are behind a router and you'd like to be able to access them from outside? Will ssh work? Are there any settings that need to be made on the router in order to access your machine? Thanks!

  You can do this. Suppose you have an AirPort Extreme base station. You could configure it to hand out DHCP addresses up to a limit such as 192.168.254.148, but set up a network location on your desktop Mac with a fixed IP address above that range. Then, use the AirPort Admin Utility to forward SSH (port 22) to that machine.
  
  To set this up, select Show All Settings, then click Port Mapping to specify a public port (what the outside world connects to), as well as the private address and port. People outside your network need to connect to the Public (WAN) address shown in the Show Summary screen.
  
  If you have a non-AirPort base station, see the manual that came with it for instructions.

  Thanks, bjepson - I have a LinkSys Cable/DSL router (BEFSR41) -- I've gone through the manual, but it is a bit confusing to me.
  
  Here's what I know:
  
  My cable modem provides a DHCP address to me. Looking at the web based router management utility, I can see that I have both a WAN and a LAN address. Will the WAN address work? The utility also mentions something called Remote Management -- currently it's disabled. Should I enable it? Sorry for my lack of knowledge on the subject, and thanks for your help!

  Google found this for me:

  Many Thanks! :)
  
  I've made the appropriate config settings as per the document (and I also have a static IP assigned behind my router now, thanks to another Linksys knowledgebase article I found.) Hopefully it will all work once I test it out from work. :)
  Are there any specific port(s) for using applications like Remote Desktop or Timbuktu?

  Glad it worked! I don't know the ports that Remote Desktop and Timbuktu use, you'll have to Google for them.

  Yay! I was finally able to ssh into my machine from work. I found a useful website called no-ip.com that assigns a pseudo name that's easy to remember instead of having to remember the WAN IP address if your cable modem/DSL switches it every few days.
