2.6 Limitation on external connections

Let's add in "Group2" a new line - "L10". Remove "In" and "Clients".

In "L10" create new group "Group5" and add in it two lines - "L11" and "L12". Into one of lines insert service "Message" with the text "Access denied".

At once for "Group5" add selector "Servers".

Similarly lines "L10" in "Group2" create one more line "L13", but with selector "Ports".

Now it is possible to return "Clients" and "In".

Let's specify, to what clients we’d like to limit access on servers, and to what - on ports.

In selectors "Servers" and "Ports" check box "Auto addition" it will be possible to observe to what servers and on what ports external connections are carried out. And if opposite to a name of a server or number of port to choose line with service "Message" then access to such resource will be closed.

If to arrange groups one in another (as at limitation on time, see 2.5) it is possible to achieve limitation of access to the certain ports of the chosen servers.
