Hi guys
i want to manage 2 server with mikrotik. i plug 2 server to mikrotik port and one cable from internet network,
how can i active internet for two server? i used bridg but its make gateway packet lost . is here any idea for this ?
Bridging will work fine. I use bridges often
i rout /24 valid ip with bgp and bw control for 20ip , and use 1 gatway and 2 interface. but mikrotik crashd after 16~20 days . i lost 1 mikrotik 750 every month 
OS crashed
I think I have had one MikroTik die… ever. We run quite a large number of them. The one I lost was a 495AH and it would not post even through the serial cable. It is extremely rare to even have to power cycle them. I generally power cycle the routers when I upgrade them which is often about yearly. I would highly recommend looking into your power source or looking into physical conditions like excessive heat or ESD or other surge over Ethernet.
