So, for example, for 207.xx.xx.102/24 assigned to the public interface netmapped to 172.20.103.102/24 works great. Steps how to configure Dst NAT in your Mikrotik Router, using DST Nat you can view your Office/Home CCTV Camera from any time anywhere using any laptop and mobile. I'm fine as long as I assign a corresponding public IP from the /24 space that I'm using in the /24 netmapped private space. To view the port 37777 tcp is enough, if there are many cameras behind the router, then you can forward the ports 37779 tcp, 37979 tcp, etc., while the ports must be changed to the same ones on the cameras.Sounds good, but I can't seem to make this routing work. To Addresses: 192.168.88.1 (internal router ip)įor example, to DVR Dahua you need to forward ports: 80 tcp, 554 tcp, 37777 tcp, 37778 udp. Address: 192.168.88.0/24 (internal network) you can assign ip1 (192.168.1.1) to mikrotik interface and use dst-nat to redirect to another ip2 (192.168.1.160) /ip address add disabledno address192.168.1.1 network192.168.1.1 interfacee1-lan /ip firewall nat add disabledno chaindstnat actionnetmap to-addresses192.168.1.160 to-ports3389 protocoltcp dst-address192.168.1. To access the external IP of the router from the local network, you need to add two more rules. ![]() I will give several examples of ports: 3389/tcp – remote desktop, 80/tcp – web server, 23/tcp – telnet, 161/udp – snmp, 22/tcp – SSH, 1433/tcp – MS SQL Server, etc. To Addresses: the IP address of the network device/computer within the network from which you want to forward ports, for example 192.168.88.250 interface: the incoming interface on which the above port is listening, for example “ether1-gateway”. NETMAP Configuration Example: /ip firewall nat add chaindstnat. chaindstnat actionnetmap to-addresses192.168.1.11 to-ports21 protocoltcp src-address0.0.0.0/0 dst-address1.1.1.1 in-interfaceoutside dst-port21. Port: destination port that will be visible from the outside (1 – 65535). This method mikrotik router called netmap. The only way to do it in Mikrotik is if you're using your Mikrotik as the DNS resolver, you can create static entries for the interesting 172.x.x.x hostnames of the remote site, and the Mikrotik will give these answers instead of going to resolve them. Chain: dstnat (means that the connection will go from the external network to the internal).ĭst. ![]()
