Okay I have questions before i think of buying it..
Requirements: - Can it handle 100/10 Fiber connection, so it not would be bottleneck.. - Does it have fan cooled, or passive? - What i did forgot to ask ;P
Take a look at this thread »USG series FW 3.00 Comparison All the speeds are both ways, USG50 is rated 225Mbps meaning 125Mbps one way so your 100Mbps connection should be just fine however any UTM services will cut the speed significantly. USG50 has no fan (I'm personally managing one USG50 and am positive on that).
