A member of the defending team needs to host a match with the following settings:
Play -> Private Match -> Game Setup -> Game Mode: Domination
Then click "Game Rules", and make them the same as the following:
Everything is default except for the following:

Challenging side always starts as Rangers.
Once you have set the rules correctly, you will need to invite all the players. You should just need to invite one of the captains from the opposing teams, they can then invite all of their team in.
Once everyone is into the lobby, you can start the game, IWNet will decide who has the best internet and they will host the match, so hopefully atleast one of the 10 players has a decent upload speed.
I don't believe there is a way for the players that join the server to verify the match settings. So, once the match starts it's easy enough to see if anything is not done right.
If there are any problems with the settings you need to tell the other team immediately and you can re-create the server. Otherwise it'll be assumed you are happy with the settings, even if they are slightly wrong and the match will count. Do not bring up a dispute for incorrect rules, as no match will be over-turned, the score/win will count.
