I have a Mikrotik unit that had been running pretty flawlessly for almost a year that has failed 3 times in the last 2 1/2 days or so. The unit is a RB532 with MT 2.9.28 on it, 32 MB Ram, 265Mhz processor, Atheros AR5213 radio bridged to ether1, WDS, associated to its sister unit for a ptp link.
When it fails, I can ping and log in to the radio from either interface. There doesn't seem to be anything out of the ordinary, I have all logging set to remote, and nothing shows up on the log server, but no traffic seems to be bridged between the ether1 and wlan1 interfaces. Ping watchdog doesn't do any good, since both interfaces work fine, and pings from the unit to network devices on either side of the bridge are successful. Pings through the unit fail however, as does all other traffic.. Power cycling the unit, or logging in to it and executing a reboot fixes it. Any ideas what is causing this to happen, or how to prevent it? I suspect malicious packets being sent through (or to.. although it has only an rfc 1918 address on it) the unit as the culprit. I do have a few firewall rules on it, although that is minimal. The last two times it locked up were just before 5:00 pm. Maybe when the kids got home from school and someone turned on a virus infected computer?
