Hi

If I have a router I like decide how I define the different networks.
In a "normal" router it i not problem.

And it is an absolute normal requirement to deny accessing speciel web
pages - for example sex or game sites - without reference to connecting to
blue or green network, using LAN or WIFI connection.

I have two user networks, which must not access each other unless using
special protocols or computers, so I cannot switch them in the same
subnetwork. And I have to filter accessing special web sites.

So I have four ports: two equvivalence user networks (blue and green), a
DMZ (orange) anf the Internet (red). This is the task.

best reg.
