Hi all, quick question concerning an Edgerouter Lite.

A current Vodafone Fibre customer will be changing to Spark, and I'll need to re-configure an ER-3 Lite to work with this - that should be no issue, remove the IPoE interface and add a PPPoE one I guess, I'm just wondering about the firewall.

This router was setup using the standard built in wizard - does anyone know if I will need to do anything with the firewall config to get it working correctly with the new PPPoE connection? I'm OK on the basics with these routers, but not a lot more. 

Thank you!
