Help regarding DVRs behind RB450 G

RouterOS General
1

I currently have the following setup as under:
DVr.jpg
We have given various bandwidth pools for all users using hotspot.
Management gets 1 Mbps Upload/1 Mbps Dwnld
Office Staff = 256K/256K
Students=96K/96K
and so on

Now we are placing CCTV cameras which would be connected to 16 channel DVRs total 4 in no. Model Dahua 1604LE-A

How do we configure 450G so that we can view the DVRs remotely or on PDAs.

Thanks in advance

Configure port forwarding and assign a port to each DVR. Example : xx.xx.xx.xx:1030 to dvr 1 xx.xx.xx.xy:1031 to dvr 2 xx.xx.xx.xz:1032 to dvr 3.
