i was wondering how can i make my MT ‘invisible’ from the winbox discovery interface? For example, i have two WLAN networks. If in first (in one subnet) my MT can be discovered, if another (different subnet) my MT does not show up.
There are different options to discover your router.
First there is the Winbox Service (tcp 8291) - can be blocked by firewall (allow your management ip addresses and disallow everything else for example)
Second there is the mac-winbox service which you can find under /tool mac-server mac-winbox.
Third option is the mac-server service which you can find under /tool mac-server.
Both the second and third option are MAC based protocols - that means you can not filter it with your ip firewall (atleast not without enabling ip-firewall on your bridge). But you can use the setting in both options to define allowed interfaces (you need to set a list under /interface list first)
