ALIX 2D13 best for what it is?
I have a need for a small, quiet PFSense platform to push 50MB and 50 users max. I will need to install the tftp option and keep the local VoIP config files on it.
Is the ALIX the best for this?
I assume you mean 50Mbps? If so then you should be OK. According to Netgate:
Maximum throughput with filtering enabled:
NAT - 85 Mbps
Routing - 85 Mbps
Bridge - 85 Mbps
50MB might imply 400Mbps which the ALIX can't cope with. :P
