I have two Routerboards 411A (MT 3.10 L4) linked together, and one of them is set to bridge lan and wlan interface. Bridge works fine, but I cannot access other RB using Winbox and MAC address.
Neither of RB’s have IP, so I have to access them from PC using Winbox and MAC addresses. PC accesses RB2 correctly, but it cannot access RB1. It sees it (when i click on […] button I get other RB in a list but when I try to access it I get error Timed out!
When I connect PC to RB1 on its LAN interface, I can access it using Winbox and MAC.
Is this limitation of the bridging in MT, or there is need to do some more settings to allow Winbox to access MT on its MAC over the bridged wireless connection?
Winbox uses MAC (udp packet broadcasting) to get a connection to a locally connected Routerboard. Once you get a connection you immediately give the interface an IP address in the same subnet as your PC connection. Then you disconnect, reconnect to the IP address instead and start playing. From then onwards, the connection will be reliable. Unless you make a mistake configuring the firewall, in which case you can lock yourself out!
So, MAC connection is just for getting a connection to the box before it is given IP addresses very soon after powering up for the first time. It is not for use as a normal ‘day to day’ connection system to routerboards across your networks.
You will need to assign IP addresses to your interfaces and connect via ‘normal TCP/IP’ for you to connect reliably.
