How can I access a programs web interface from home?

[Capt Crunch]

So two programs I use, Transmission and SABnsbd+, have web interfaces. It seems like this is tailored for use from another computer on the network.

I would like to use the web interfaces to control my home computer while I am at work. To do this I think I need two things:

1 - a static IP. I think I can use http://www.dyndns.com/ to achieve this.
2 - somehow make some password protected entrance so that I can connect to my home computer securely.

Ideally, I'd like to access a URL that is my home computer, type in a login and password, and be presented with the program's web interface.

How do I do this?

EDIT: I've considered logmein.com to do this, but it is too cumbersome and slow.

Important question: do you use a router for your home computer, or do you plug it directly in to your modem?

Sorry, I should have mentioned that. I have a timecapsule.

Then you need to forward the appropriate ports. Transmission's web interface by default uses port 9091. I'm not sure about the other app, but Transmission allows you to set a username and password on the control page.

So let's say it uses port 9091. Then to access it I would type in:

http://myip:9091/whateverurlTransmitlikes

I would then be prompted to type in a username and password dictated by transmission. Does this leave my computer vulnerable?

Short answer: no.

Long answer: yes.

That is, if you have other ports forwarded. If someone gains unauthorized access to the Transmission web interface, all they'll be able to do is start and stop your torrents.

ok, so I successfully set up dyndns and I downloaded a port-forwarding tool.

I managed to get Transmission to work. I type in http://mydyndnsurl.org:myport/transmission Then I enter my login and password and I'm good. When I do the analog for SABnzbd, it says it can't connect to the server. I did the exact same procedure for both. I double checked the port numbers a millions times. Any ideas?
