HowTo: Significantly improve slow throughput on EdgeRouter Lite PPPoE

When you add some rules into the firewall, it can be the case that Hardware Offloading is disabled without your knowledge! Before we re-enabled Hardware Offloading on the PPPoE client it was only able to handle about 140-150Mbps of throughput. After we re-enabled it, the throughput went up to 296Mbps on a 300Mbps BT Openreach FTTP circuit.

Try this from within the CLI to enable Hardware Offloading for the PPPoE Interface :

configure
set system offload ipv4 pppoe enable
commit
save
exit
