1. Make sure you disable the firewall on your laptop, OR enable UDP port 69 on the firewall configuration.
2. Is the physical link actually up? If not, Make sure that you are using the right type of cable. You might need a crossover cable. Although I doubt that this is your case (since laptops nowadays usually come with Auto MDI/MDIX NICs).
If nothing works, then what piece of software are you using for the tftp server? Make sure it's a TFTP not FTP. They are different.
could you please send a config how udp port 69 should be enabled on the firewall.? Thanks
I was talking about the Windows firewall. But since you already have it OFF, you don't need to enable port 69. Furthermore, you don't need to enable port 69 on the Pix either (Unless you explicitly denied that traffic as Smurf noted).
