Mac Telnet Boken in 5.18?

I have a RB433 and a SXT I put 5.18 on. Every thing seemed to work but when I tried to get in thru ssh IP Telnet and Mac Telnet all failed. Is this Broken?
I went out to the SXT removed the default firewall settings and down graded it to 5.17. Some things started to work, ssh ,telnet but not Mac telnet. Accessing was thru the rb433 to sxt when testing. I have not down graded the 433 yet. Will do that next and see if that brings the rest back.

i have the same problem in on rb411ah try to conect to rb711-2hn, the other ratio let me login and pass but no conect any way.

I have upgraded to 5.19 and still cant get into the client radios. What is going on here?

Look at tool → mac-server. It is most probably set to ether1.

You have to change /tool mac-server set 0 interface=all. Or change it in winbox. You will be able to login using mac-telnet too.
