What happened to Portshield? We use the TZ series primarily, but recently purchased an NSA 2400 for our office. I need ports X2-X5 to be a separate LAN2 with a separate IP range. I do not want to use another switch to connect 3-4 servers together and then go through X2. I want to plug each server into X2, X3, X4 and X5, they all be able to see each other, but NOT the LAN and use the same gateway such as 192.168.50.1. Possible?
