In my country (New Zealand/Australia) we have an allocated amount of bandwidth we can use per month or we get charged a lot of money, and downloading games off Steam often uses a lot of bandwidth. Our ISP decided to make their own server for Steam to save bandwidth when downloading off Steam, but to save all of the bandwidth when downloading off Steam you have to set up an Outbound Rule with the firewall to block certain Steam IP’s. They give you a guide on the website of how to do this with the default windows 7 firewall. Since I am using Windows XP I had to download a firewall which blocked Outbound Connections so I downloaded the free version of Comodo Firewall. I found out where to make an Outbound Rule but I’m unsure of how to setup the IP’s and Ports.
I get this far and am not sure where to go from here,
I think the guide should give enough information on what IP settings to use if you understand it, if not please tell me! ;D

Important is:
Outgoing: You are the source, the remote IP in your instruction list is the destination.
(Ingoing, if thats necessary): You are the destination, and the remote IP is the source.
Look carefully on the notifications about “TO”(destination) and “From”(source) in that list. Because, they call it outbound, but theres also a rule where 58… is the source (“from”).
Now look at your picture and on the instructions from your provider, and insert the given numbers, in the right place 
I just give a usefull hint. I dont use a capped internet connection myself. If theres a monetary aftermath possible, make sure that you understand what you do. Follow the list of your provider, and make sure, related to comodo, that you know for each rule who would be source and who would be destination.
If you have any question left, ask here about comodo, and ask your provider for his rules. He should give you also necessary informations about what you should BLOCK from/to steam.
Its strange to write about capped internet… hope i could help a bit.
EDIT: When you made your rule set and are trying to load a game, keep an eye on the connection list of comodo. There you can control if the “big amount” of data is coming from the right IP adress of your provider then.
Capped internet is a nightmare.
Thanks for the reply ;D, I set the Outgoing Port in the rule to the single port of 80, and made the outgoing range of IP’s into 2 different rules, one for above a certain range and one for below. I left Source IP’s and Ports as “any” because the guide doesn’t mention them, does it sound like I did anything wrong?
Also, there are 2 instances of “Allow All Requests” with my 2 rules. Do these cancel out my rules? Do I need to rearrange the order in which they are listed? (The rules are at the top because I assume it’s a priority list with top being highest priority)
Yes, the order in which the rules appear is VERY important.
An allow rule on top will allow traffic, even if you later would make a “block all” rule under the first rule.
For your specific question about, if all is like it should: Tell your provider which rules you made, and if that fullfills the requirement. They would charge you if somethings wrong, they made only a “how to” for windows 7 and vista firewall. So its them who should tell you if all is ok.
But dont forget, whatever they say, check when you download something, that it is coming from their ip! And if you have a “live check of costs”, have an eye on that also.
PS: I wondered why you speak about a port 80. Because when i read the instruction first, there was a port 27030 mentioned. Now its 80:
("- Change protocol type to “TCP” and under “Remote port” select “Specific Ports” and enter “80”, then click “Next”.)
Thats why i repeat, ask them.
Here you can get any information how to make rules, but the rules must be clear. They should tell you:
Which port and adresses to allow, which to block. Both for outgoing traffic, and (to make it sure) for ingoing traffic also. Just this basic informations.
Thanks for all your help, I will talk my ISP about it! ;D
