Hi every one!
This is my first post.. and if is the rong place forgive me!
I have a problem with winbox. When I try to acces my rb750 wia winbox using mac address i recive an error like this:Could not connect to xx;xx;xx;xx;xx;xx(poer20561)-timed out!.
Can enyone explain me what is the problem?...because if a use ip address instead of mac adress i can access my rb750 whit no problem. I,m using windows 7 ultimate for this...

Check your Windows firewall !! >> Turn it off or make exception

I have done that, windows firewall is off, but still the same problem, I have to wait almost a minute to appear something on my winbox....if I"m lucky. The bottom line is: if I don"t now the ip of the mikrotik i can not acces the device wia winbox.

Right now I switch my laptop with windows 7 with another one with windows xp and whit this i don't have any problem conecting to mikrotik rb750. Does anybody has the same problem? IS ther a bug with winbox and windows7?

Hello,

are you running virtualbox on windows 7 by chance?

I had that problem as well. Somewhere in the forum, someone suggested disabling the virtualbox interface.

I did that and now I do not have problems.

If you are not running virtualbox, then I am not sure.

After you disable it everything is OK? If soo can anyone tell us why is this behavior with virtulabox on ours systems?
