Hello , i wanna write a proxy for a program but i cant change to ip&port where the program connects to , so i want to "catch" the outgoing data and make it run through my proxy oO

theres loads of these example firewall apps on pscode.com but most of them only work on win XP, what app is it for? a lot of apps store the IP/port settings in the registry, such as msn messenger, internet explorer. so you could change them there to connect to your proxy

its for an onlinegame called ragnarok , the client connects to a loginserver , a charserver and than to a mapserver.. i can change the ip of the loginserver it should connect to , the loginserver tells the client the ip and port of the charserver ( managed to edit packages to connect to localhost ) and the charserver tells the client encrypted the ip and port of the mapserver. I dont know how the encryption works , so i wanna proxy the connection before it connects to the mapserver .
Yes it is hacking but not bad , i want to connect my vb program after that to a mirc socket and send data between ( chat messages ingame to irc and other way round )
