Why Tftp won't work globally?

I have tftpd-hpa with inetd installed. Locally (tftp ) works fine. Port 69 is opened and worked both on input and output. Using

netcat -ul -p 69

I can track incoming file, and yes - incoming file is correct both with size and name. Configuration is default from every manual

tftp  dgram   udp     wait    root  /usr/sbin/tcpd  in.tftpd /tftpboot

Mode 777 and owner is nobody, while tftpd-hpa and openbsd both are root. Thx
