TFTP ROS 6.40.1

RouterOS Beginner Basics
1

Hello together,

I have a little problem, so I have 2 RB1100AH X2 Routerboards. One of them have ROS 6.6 installed and the other ROS 6.40.1. The Router with ROS 6.6 works, but I have many problems with the usermanager, so I would have a second one, that I can reset the first an make a new clean configuration an the second reason i have a board so i can change it fast, i one dosnt work.

But the problem is the board with ROS 6.40.1 I can not downgrade to ROS 6.6 and with this board, my tftp server doesnt work. It menas it looks the used option 18, 66 and 120 dont work.(the log says unknown (120) and so on= So I changed the option 66 to 150, but nothing,… what can I do?

Sorry for the bad english, I hope you understand what I mean.

When you want to have an answer, you need at least to try to obey the guidelines for posting.
You should include the relevant part of the configuration that works on one router and not on the other.
(DHCP and TFTP settings)

I found it… the calculated HEX Value for TFTP Server adress (in ROS 6.40.1)was false. I used the value from old version and now it works

Thank you very much…
