Archer 2600v Problem with TFTP ALG
Hello,
I have succesfully used the 2600v (please note, that it is not in the drop-down list, so I needed to choose 2300, which is not right) router with Deutsche Telekom DSL connection with IPTV for three years already. Now DT changed the Media Receiver to a new 401 model. It uses TFTP to boot, and this does not work. I have used Wireshark to capture the connection, the results are as follows:
1. MR401 sends request to server (62.155.251.136), port 69
2. Receives DOUBLE (?) option acknowledgement, one from port 33898, one from port 33899.
3. Sends also double packet 0 acknowledgement to both ports.
4. In a second, server repeats option acknowledgements. That shows, that it have not received packet 0 acknowledgement.
I have tried to show the Media Receiver in net as DMZ, that did not help. I also tried to make this TFTP dowload from a WIndows computer in my network, with the same result: seems that server does not receive ACK.
I have no idea what should I tune to make it work. TFTP ALG is on on the router.
Regards,
Dmitry
