Dear support,

I bought one mikrotik router board RB751-2HnD

i use ip 118.103.176.10 on interface WAN(IP isp)
i use ip 192.168.1.1 on interface LAN

i use ip 192.168.1.2 in my DVR connect to my LAN

can some one help me , how can i do nat rule ?

Thanks

This is what I did to access my webcam from outside the network.

Go to /IP Firewall NAT and create a new rule.
Chain=dstnat
Protocol=tcp for my camera
Dst.Port=the port you have set up for your camera.
In.Interface=ether1-gateway
Action=dst-nat
ToAddresses=192.168.1.2
ToPorts=again what your port is for your camera.

Thanks.

i will try
