If you need to check quickly how well the Internet connection of one of your pfSense routers is doing , why not use Speedtest ? And this just requires installing a small package on the machine.
If you use or plan to use a fiber network card such as the Intel E10G42BTDA – Intel X520-DA2 with a PfSense firewall (such as our SolidRouters), you need to adjust the /boot/loader.conf.local file with informations such as :
vm.kmem_size="435544320"
vm.kmem_size_max="535544320"
kern.ipc.nmbclusters="1000000"
kern.ipc.nmbjumbop="524288"
hw.igb.fc_setting=0
hw.ixgbe.num_queues="4"
Values are to be adjusted according to your setup. The last line is relate to quad ethernet network cards from Intel.
Load balancing & dual wan are magic and pretty helpful. If you found this post I guess you know what it is but lets summarize : you have several internet connections and need to balance the outgoing trafic of your users to these connections.
In PFsense 2.0 it is a bit different in the making than with previous versions.
