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.
