I have a trouble. My FTP server must have an active ftp connection. It means what in ipfw rules I must allow outgoing connections(like ipfw add allow tcp from me to any keep-state). But I don't want use this rule. I want to restrict my outgoing connections. Is FreeBSD have a feature for this situation? P.S. Only for test we developed little root-kit, which can use only outgoing connections. example: 1. rootkit gets a command from remote machine 2. do this command. 3. connects to remote machine and returns result. So we havn't got connections to my server, only outgoing.. Best regards..
