Hi,

I've now had several MikroTik devices I couldn't connect to using Winbox and MikroTik MAC address. It doesn't even find it in the neighbors. If I plug my computer to a switch (ie. Cisco) and the MikroTik to the same switch (in the same VLAN) I can see my MikroTik device in the neighbors and I can normally connect to it.

It doesn't happen always and if I use a different computer I can connect to MikroTik just fine.

Any ideas where to start looking? It is obviously a problem with my PC but I don't know what could be the cause.

I have seen some strange behaviour with regards to neighbor discovery not working because the network interface isn't active because it has no IP-configuration. But that doesn't explain why it works when connecting trough a switch.
