I'm starting to run up against more and more speed problems using older firewalls or UTMs with newer VDSL or fibre connections - particularly with PPPoE.
Example - a Netgear FVS318G which is rated for 25mbit WAN throughput only gets up to about 10mbit download speed on a Vodafone BizNet connection which is capable of 30mbit download speeds.
Can anyone advise on a decent range of UTM and firewall devices that can cope with the throughput that customers are expecting now? Typically these are small offices with maybe 5-20 users so budgets aren't astronomical.
I have had some success with Netgear UTMs but they seem to be nearly impossible to get hold of for some reason. We have some Juniper SSG20s and a couple of old Snapgears still hanging around that really need to be replaced. What have you used successfully?
