*** Some configuration on Netopia modem:

*** Some configuration on Fortinet router:
#1.Operation Mode: NAT
Network Interface: WAN1

#2. Network -> Interface -> wan1
Addressing mode: PPPoE
[v]Restrieve default gateway from server.
[v]Override internet DNS.
#3. Network -> DNS
Use DDNS: checked
Interface: wan1
Server: members.dyndns.org and dnsalias.com
Domain: yourDDNSaccount.dyndns.org
Username: yourDDNSaccount

(2)ATT ADSL line using PPPoE with NAT DHCP on Netopia Cayman 3546 Modem.
The Fortinet FWF60B WAN1 have to use DHCP,
but the DDNS will get a private DHCP IP from the Modem.
So, it is not recommend to use the mode if you need to use DDNS.
