Hoping the forum can help. A question on cutting over an Edgerouter Lite to directly connect to the ONT. ISP = Spark UFB. 

Current config is ONT > HG659b > ERL and I want the HG659b out of the mix connecting the ONT directly to eth0 on the ERL. 

I don't want to run through the WAN+2LAN2 wizard for setup as I don't want to loose the existing config of the ERL. Can I simply add a new  PPPoE interface to eth0 VLAN ID 10 (eth0.10) and then directly connect the ONT? I am doing this all remotely and just want to get the person at the other end to re-patch once the change is committed.
