Hi,

In SPA122 with fw version 1.1.0 (11) tftp client is not operative when DMZ is Enabled, provisioning not working.

When DMZ is active, the request to SERVER TFTP to complete successfully but the response sent directly to the private IP (DMZ).

With fw version 1.0.2 TFTP cliente with DMZ enabled working properly.

For now. the solution is downgrade to fw version 1.0.2 (006).

Regards,

Hello again,

With firmware version 1.0.2 is still the same problem (to be downgraded by the SPA122 not update with the correct settings and did not activate the DMZ).

I think the problem is that the response from the TFTP Server uses a random port (which is different from UDP port 69 with which it established the connection). If so, the SPA122 is not working as the older models (SPA2102 or WRP400). We currently have over 400 equipments with DMZ enabled that are updated periodically with this TFTP server and have no problems.

Cisco needs to solve this problem soon.
