MikroTik shows up in discovery, but unable to connect

I’m trying to reach a Master and a Slave link, both shows up with MAC, IP, Identity, Version etc etc.

But I’m unable to connect and get timeout when trying MAC and or IP.

Any ideas? Are the devices online when they shows up in the list, or is it just a cached history?

likely a firewall or service setting, if the list you’re talking about is the “…” scan button. the list at the bottom of the window are ones you’ve clicked save for. can you connect via its web interface?

Yes it’s the scan button. So if both master and slave shows up, they are actually “alive”?

I can’t connect to them on web interface, neither does they reply on ping.
Any tricks to reach them?

Yes, it means they’re alive or at least responding to that scan function. See: http://wiki.mikrotik.com/wiki/Manual:IP/Neighbor_discovery - anything that shows up from the “MNDP button” scan has neighbor discovery enabled on the interface shared between you and the Mikrotik.

If you can’t reach it by normal means you’ll need to know what the rule is that is denying you, or perhaps the MAC server function has been turned off altogether http://www.mikrotik.com/testdocs/ros/2.9/tools/mactelnet.php

Physical (serial port) access may be required.
