New to Sonicwall and need some help.

[sapper1]

I have a Sonicwall NSA 240 and I need a little help. Currently anyone who tries to open a RDP session from the outside is allowed. I want to limit that to only certain IP addresses. How would I go about doing this?

Create a new Address Object under the Network section for the specific IP addresses. If they are in the same range, then you can define the range. If they are all different, then create different Address Objects for each IP address (name the object something you will understand if someone else had to come in after you). Then create a Address Group putting all of those Address Objects you just created into this new Group (maybe calling it Allowed RDP). Under the Firewall section, go to Access Rules and sort by Matrix (I find this way easier to view). Find the RDP access rule and click on the little pencil button to the far right (to make edits) and change from source "Any" to the new Group "Allowed RDP" (in this example).
