I do have a legit reason for this. When i ban someone from the game server, it bans the ip address. But that info is only stored in memory and is lifted once the game is restarted.

Does anyone know of a way to get the public ip when the player connects.
So if i ban a player, i can save the IP to a tmp file and have the app auto ban them if they rejoin at a later date.

Im sure its possible but i have no clue where to start. I cant store the ip from reading the memory, i tried.

Load the ban list when you start the server? It sounds like you already have a way of getting the IP address.

Sure i can get the ip after the person has been banned. But all that gets wiped when the game restarts. I cant get the ip before the ban so i have nothing to compare to. The ip doesnt exist in memory before the ban.

Hence my obvious confusion. You are getting the ip when you ban so you should be able to get the ip before you ban. What is your "game server". Is it your own or someone else's?

My point was that if you are holding the ip in memory then you could write it to a ban file and load the ban file upon server startup. Anytime there is a request, make sure the ip is not in the ban ip list

Learn the server software you're using, we can't read your mind and probably won't do the work for you anyway.

Thought about a firewall rule that blocks their ip ?

Yea i thought about that and i joined the server with my laptop firewall turned off.
Maybe its my firewall on the server pc, i did just update it. I checked my router logs, nothing gets blocked.

I was thinking about adding a firewall rule to the server that blocks the banned person's ip, not a rule on the client

for example, when I ban someone on this website, I use "iptables -I INPUT -s 11.22.33.44 -j DROP"
(These get removed on reboot, but if I want to make it permanent, I add this line to a init file)

I believe windows also supports a commandline access to the firewall, and the ability to block specific ip's

That might actually do it. I never thought of that.

Another route you could take is modding the server binary and creating your own framework around the parts you need to work with. Something like SourceMod for games like Counter-Strike, TF2, etc.

Would require a bit more work than just adding people to a firewall list but it would allow you to do a lot more in the end instead of just banning as well.
