2) Pretty sure 10.20.20.2/29 will need to be added to your WAN interface
It really depends on how exactly ISP delivers traffic for the additional IP addresses. If they use "base" IP address as next hop downstream, then none of those addresses need to be present on WAN interface (even more: they should not be). If, OTOH, ISP expects to see these addresses via "ARP who has" procedure, then those addresses have to be set on WAN interface (or elsewhere with proxy ARP enabled).
