Where is the users current IP stored?
 

Hi everyone,

We are running two servers on the internet, one game server and one forum server.

Both are under constant DDOS attacks, while the forum server is coping (thank god for linux and IPTables) the game server is under alot of stress.

My plan was to do an export from the "USER" table, listing the username and ipaddress field. Then import this into the 2nd box's firewall and use a whitelist so all other traffic is blocked apart from forum users, however it appears that DHCP users are unable to connect.

On closer investigation it appears the "ipaddress" field in the "users" table doesn't get updated when the user browses the forum, I guess this IP address was their registration IP.

So, is the users current IP address stored in a different table ? or would I be able to add a SQL UPDATE ipaddrerss into users where username=$name (or similar) somewhere into a php plugin/template ?

Thanks in advance - I really hope someone has a good idea here so we can block this DDOS once and for all.

Regards
