How to have open ports on Draytek router, to only be accessible from a specific source rather than from anybody/anywhere?

hi guys

We have ports open on a draytek 2830 router, so that anything that is accessing the external IP along with the open port, is then forwarded to an internal IP on the LAN.

Now, at the moment anybody from anywhere can access these open ports. How can I configure the firewall so that these ports are only accessible from specified IP's on the draytek?

I've gone into the FIrewall->Filter and I've enabled the filter. I've then selected 'WAN to LAN' and made the source IP the address I have been given which that person will access it from. Then I've permitted the destination to be any (just for testing purposes). And I've allowed the 'pass immediately' as the filter. But it does not allow access the network.

Any ideas on how to make this work?

Thanks

Deepin, thank you so much. The only thing is I can't see any of the pictures. I'm assuming this is the Draytek site I can go to and search the same?:)
