Thanks for your reply. I am afraid that 10~20Mbps through VPN is indeed the best I can get. That would be nice if I was lucky enough so that someone from netgate / pfSense could confirm that here. Can you please provide a link containing informations regarding the ARM crypto driver and its integration into pfsense ?
But without VPN I think there really is an issue with the maximum 25Mbps I get. Should be more than 100Mbps i think :
https://netgate.com/docs/sg-1000/faq.html#what-should-my-speed-test-results-be With a basic firewall setup we have shown it can pass around 130Mbit/s. In other conditions, the speed may be higher or lower depending on the firewall configuration, enabled features, environment and testing methods.
https://netgate.com/products/sg-1000.html Using pfSense with the default ruleset offers performance exceeding 200Mbps.
I guess you refer to SG-2220. I considered it but it's for home so I try to reduce the cost. And if I'm not mistaken we still don't have precise informations about that Intel Atom C2000 broken CPUs issue.
