Hi guys,

My first post, need help if possible.

I need to configure a Draytek 2830 to block all traffic through port 1720, except 1 single IP address.

Any ideas on how to do this, I can only assume this is done via the firewall option, however the whole screen baffles me.

Any help would be appreciated

Hi
There are a couple of ways you can do it but heres one of them

NAT - Create the open port to the LAN address

Firewall > Filter Setup > Data Filter > pick 1st available policy



then create the allow rule




You could probably do it with one policy rule and use the invert selection option but I think the above is clearest.

Thanks sicon,

Worked a treat, very clear.
