Hi All,
I need some help,
I was already setup the IPsec withe the Cisco device, the peers Tunnel was working properly. when the cisco ping Mikrotik I can get the ESP packet, but when I ping to cisco I can see the mikrotik was sending out the packet, but cannot get packet what I am use packet sniffer. And cisco side cannot get any packet from my side. I tried use the 2 Mikrotik to make the IPsec before, everything was working fine up there, I was so confuse about this, anyone can help me…I will appreciate that… 
Sorry for my bad English…
