You will be fine creating a NAT for a small network and using IPSEC; just don't expect to get close to 1gb throughput. This applies for most hardware, esp. cheaper hardware. These boxes use 82574L, which is a low-end/integrated NIC chipset. If you want higher throughput you can look at different network cards, like the Intel 82571 or 82576, though you will need to make sure the SuperMicro chassis/motherboard supports an expansion card (some models do not have a riser or the capability for a riser). EXPI9402PT (82571) E1G42ETBLK (82576) I have around 20 endpoints on my networks using this box as a router and IPSEC termination point, and it handles it well. I have 4 separate subnets the router routes between and the router uses 1 interface as a trunk and vlans on the switch to handle all the routing. Axton Grams
