It isn’t clear from your description if the Mikrotik router also has a direct connection to network 192.168.1.0/24.

1- i have one mikrotik ,
i configure ip 118.103.176.10/24 on interface WAN
i configure ip 192.168.10.1/24 on interface LAN
note:this mikrotik i disable DHCP.

2- i use cisco linksys router
i configure ip 192.168.10.10/24 on interface WAN
i configure ip 192.168.1.1/24 on interface LAN

3- i use DVR-camera
i configure ip 192.168.1.30/24
port :5566

DVR connect to LAN port cisco linksys router , WAN port cisco linksys router connect to LAN port mikrotik.

i need remote from interface WAN mikrotik to DVR (remote ip118.103.176.10 can into 192.168.1.30)

Thanks

You will need to forward the required port(s) on both the Mikrotok and Linksys routers but you don’t say which port(s) is/are required.
