(adsbygoogle = window.adsbygoogle || []).push({}); So despite the many threads on this question, no one has ever really had a definitive answer to how to lock a lobby on CoD 5. I posted this in an older thread already, but i think that some people who could have used the information perhaps over looked it because of how far it was buried. Anyway, here is a list of the possible ways to lock a lobby on cod 5:

1. Upload a video to youtube or any other filesharing website: Not very effective as it must be cancelled before the game starts and you are therefore completely helpless if someone times out or something. However, it works great as far as getting the necessary people into the game lobby before the game actually starts, but you must fill the lobby if you dont want random people joining.
2. Lag switch method: If you go into a game with 6 people and back three out while lag switching with the correct timing, the game will sometimes lock up, and only people you invite can join.
3. Forward all the ports on your router to a non-existent ip address: This is my personal method, but it has its drawbacks. First, Once you enable the port forwarding rule, only the following can connect - people who are already in your party, other playstations that are on YOUR internet connection, and other playstations sharing the same internet connection as the friends in your party. In order to be used effectively therefore, it must be combined with a youtube upload to get the people into the game lobby, then enabled right before the game starts. If done right, it works like a charm. By the way i use a lynksis router for this because unlike many routers, it doesnt require you to reboot when enabling a port forwarding rule, which would sign you out.

Here is a screenshot of my router page to try to help you guys out with any confusion:

4. Just plain luck: This is the way most of the top boosters lock rooms - they just happen to have an isp that ends up spontaneously giving them locked lobbies. It sometimes happens after a certain sequence of people leaving the game, or even just as soon as they enter the game with a party, but whatever causes it, it works the best because no random people join, but everyone who is invited can.

BE SURE TO HIT THE THANK BUTTON IF THIS HELPED!!!!!!!!!!!!!!

yes this would work on xbox as it is a setting you are changing on the router that is independent of the game console.

and also bypassing is most definitely not easier as it would require deleting the game data which includes all three map packs from all three of my systems which would equal 6 gigabytes of redownloading if i ever wanted to do a winstreak or something. sorry a worthy theory but not easier in least.

wow i remember a little while ago when i asked you to help me with this and you wouldnt. boy i love how things come full circle... but ill actually help you because i dont like being a dick. anyway if you have a linksys router which is what i use when i want to lock a lobby, go to port range forwarding and forward all the ports (1-65535) to some ip address which i know is not in use. if you dont know which one is not in use a safe bet would be to pick one that is very high up on your router's dhcp range, so if it was dealing out ip addresses in the range of 192.168.1.100-150 i would pick something like 192.168.1.149. i will add a picture to the first post to try to clarify.

be sure to thank if this helps

no the point is to block ALL the ports so no data packets can enter your router unless they are from people already in your party.

i dont know how your router is set up but all you should have to do is enable the rule
