Hi I have the vigour 2820. I have forwarded a port which works fine but I only need it too be accessed from one but despite setting the Source IP: in the filter to the required one other ips can access the service. I have a couple of pictures that may make it clearer

You should probably have a block if not further match as the first rule in set 3, followed by your existing rule as the second.
At present, there is nothing to block other addresses.

That worked fine thank you

I am doing the same thing and despite blocking traffic I can still access RDP traffic from secondary ip addresses. Can anyone help, below is my blocking rule.


Many thanks

Your problem there is that you need to set the Source Port to 1-65535, this is always random for incoming traffic like this so once you've changed that, the rule should then work.

Many thanks, this has resolved my issue
