    I don' t know any detail of this Zyxel. But I think if you use ' peer gateway = dynamic adress' maybe it expects ID settings for P1 authentication (and aggressive mode) (Is it a dynamic IP at that D-Link? Can you use this D-Link as modem-only? Then you could set PPPoE at 110C without NAT-T)

    Hi I try to set peer ID on the fortigate, but i did' nt find where: In edit phase 1, if i set Aggressive, i have only 2 choices : Accept any peer ID or Accept this peer ID The zyxel request both local and remote peer ID The D-Link cannot be used as modem-only it' s a static IP at that D-Link so i try peer Gateway = 193.x.x.161 on the zyxel that doesn' t work I' ve got authentication failure on the zyxel thanks

    Accept this peer ID -> fill with local ID from your Zyxel The local ID on Forti you can find under Phase1->Advanced->P1 Proposal->Local ID Fill this with the ' remote ID' you have configured at your Zyxel
