Reset configuration of your router to get access.

Use S301 to reset your router.
Short S301 with metallic object and apply power, wait RouterOS to finish booting, remove metallic object.
Access your router and apply configuration from the beginning.
Maybe mac-telnet will work? If the problem is in firewall - I assume you block only IP communication, mac-telnet (or mac-winbox) should still work…
hi dasiu
thanks for replying,
but the router is not visible in winbox
is there any mathod to know the mac add of my router
Of course - you should be connected to the same subnet as the router (either directly with your computer, or have any MT you can access, that is on the same subnet) - and then check.
If you didn’t disable “/ip neighbor discovery” - the MAC should be visible in “/ip neighbor” (on other MikroTik devices connected to your router) and on winbox.
You can check MAC also with arping 
.
if you are using,

Use Null Modem cable and get console output by COM port,
