TFTPD Server problem

Hi Guys,

I have a MacBook Pro running a OS X 10.7.5 Lion. I wanted to use it as an TFTP server. I set up DHCP and TFTP, it's starting ok. I can even issue "tftp localhost" and then "get pxelinux.0" and it works fine. When I start the client machine, connect it with a patch cord to the MacBook it receives a valid IP from the DHCP and attempts to get a file from TFTP server, it fails however. The log reads:

Oct 7 20:09:10 pol- tftpd[2732]: tftpd: read: Connection refused

Oct 7 20:09:12 pol- tftpd[2737]: tftpd: read: Connection refused

Oct 7 20:09:16 pol- tftpd[2739]: tftpd: read: Connection refused

Oct 7 20:09:22 pol- tftpd[2744]: tftpd: read: Connection refused

Oct 7 20:09:30 pol- tftpd[2747]: tftpd: read: Connection refused

The FireWall is shut down.

Please help
