Mikrotik 450G - how do I port forward to a webcam

Just got this nice router today but having problem configuring it for port forwarding . I have a networked PC with a static IP of 192.168.1.100 with a webcam attached. I am using www.camstreams.com for hosting and their software uses port 5700. I have reduced the IP pool range from 2-90 on the router . I have tried to create the port forwarding rule as per manual under ip>firewall>nat but cant get it to work. Could someone more conversant with this router setup give me the exact commands I need to input using the required static IP address and Port. Many Thanks

Does the PC have internet access via the routerboard and is that working?

Are you using WInbox or Webfig to configure the routerboard?

The NAT entry would look something like:

add action=dst-nat chain=dstnat dst-port=5700 in-interface=“your interface” protocol=XXX to-addresses=192.168.1.100 to-ports=5700

XXX would be UDP or TCP as required.

Hi - yes internet is connected and working fine.
Using Webfig to config.
Can you explain to me what ‘your interface’ refers to. Thanks

yes - router working fine on internet. Using webfig . What should ‘in- interface’ be? - there are numerous selectable choices. I live in Thailand using TOT fiber2U service so router is connected to a mitsibushi fiber optic modem. Have tried selecting most options but still do not get any webcam feed. CAmera and port forward work fine using my other ISP service from 3BB which is ADSL on a D-link modem/router. Simple to setup port forward on that. This is somewhat more complex.

‘your interface’ refers to your public interface (WAN).

HTH,
