HG612B bridge settings with Vodafone?

Hi all, just wanted to ask if these settings are OK and if there's anything that I should change to make sure the HG612B isn't handicapping anything whatsoever.

The modem is unlocked and acting as a modem only (disabled everything in firewall, and all relevant router functions)

PPPOE authentication is being done in the RT-AC68U.

Thanks!
