Protection of the public session from randomness [guide] (Grand Theft Auto 5)

Now, we all know that the public session with random players is the cheaters, the oppressors mkII and all sorts of other Barmaley interrupt play if you want opportunities public session and playtime with friends. Is it possible to shut out of randomness? YES!

Since we have our client acts as a server where other players connectats on port 6672, will close from foreign organisms, leaving the opportunity to play there with your friends without asking the ip address friends and their friends.

IN the screenshot see the traffic exchange between the players on 6672 port in the side of my computer on port 6672


What we need:

1. Operating system RouterOS which comes complete with MikroTik routers
2. White ip to NAT type was open, with microteam it will be Moderately open.
3. The Mikrotik router, buy model HAP AC2 from 3 to 5K rubles judging by Yandex (dual-band Wi-Fi, 4 core processor, if anyone WAN arrives over 200MB / s freely - loading on the processor is small) (if intyrnet speed is not so hot - buy hAP mini, it costs $ 20 to 69, for hap ac2)
4. To configure the router Quick Set or on the phone to download the application there zamknuty the same.

Further, in the firewall you need to create two rules:

;;; Outbox - to save a GTA Online session without randomness (coming from our GTA client)
chain=forward action=drop connection-state=new protocol=udp src-address=10.10.10.10-in-interface-list=Local out-interface-list=WAN src-port=6672 log=no log-prefix=

;;; Incoming - save a GTA Online session without randomness (incoming to our GTA client)
chain=forward action=drop connection-state=new protocol=udp dst-address=10.10.10.10-in-interface-list=WAN out-interface-list=Local dst-port=6672 log=no log-prefix=

Now more detail:
chain=forward - to forward the traffic to/from our computer
action=drop - cuts arriving and departing from us or to us requests on port 6672, it will be cut off randomness bursting with us in the session
connection-state=new hack only new connections, this is the most important! Our drone it will already be in our public session on port 6672, pass through the connection-established state (actually, we don't need to know their ip addresses, so it already knows Mikrotik), related and both rules do not touch them


src-address=10.10.10.10 local ip address of the computer from the static settings set to not change if a lot of devices sauzet our Mikrotik.
protocol=udp game needs the UDP Protocol
interface-list=Local out-interface-list=WAN - the direction of walking traffic, in this case from our computer in the world
dst-port=6672 actually the port that our client uses to connectilis players.


As can be seen emanating from our computer zablocie a whopping 11MB.

And now when everything is configured?

1. Do a clean without one session as we need to host this session
2. Recruit full public friends, they have their invite
3. Activate both rules in firewall which will close for connection-state=new in our session, 6672 port on our computer.
4. Playing without randomness, which is to cut off the action=drop, and our friends and their friends are in for firewall connection-state established, related, that is, they have already established with our port 6672 connection, and those who are not installed - they are new and their both the rules will be cut off.

If the console, for console ports, its console and substitute will work too
