Sure! You can use 1:1 NAT if you have enough public IP addresses to give 
each of your DMZ server its own, or server NAT if you need to be able to 
map individual ports on each of your public IPs to different servers. In 
any case, just assign a private subnet to your DMZ interface and add the 
desired 1:1 (or server NAT + inbound) mappings. No proxy ARP required 
for PPPoE.

Also, don't forget that you shouldn't allow DMZ servers to connect back 
to LAN (or at least only on a very limited set of ports/IPs) - use "not 
LAN subnet" as the destination for your DMZ rule.
