I have configured two vlans each with one subnet (subnet A and subnet B). I have intervlan routing enabled. I would like to prevent all traffic from subnet A from reaching subnet B but all traffic initiated from subnet B to be able to reach hosts on subnet A. This means two way communication from B to A as long as the communication is initiated first from subnet B. Is this possible with the RVS4000? I will have people vpning into subnet A and don't want them to reach my network on subnet B but I want to manage hosts on subnet A from subnet B.
