I'm trying to connect 2 fortigate units thru a VPN tunnel and one is located after a Linksys WAG54GS which provides the internet connection.
The configuration of the linksys is the following:
NAT mode is enabled
RIP is disabled
DMZ is enabled fo the IP address of the Fortigate.

internet is working on the internal LAN but the VPN won't go up...
Do you have any idea on how to configure the linksys?

no that wont work you have to make the Linksys WAG54GS as half bridge mode  so that fortigate will get the public ip.

 If the WAG54GS supports multiple public ips then you have to assign another public ip and map that to the internal ip of the fortigate. Set the vpn on that public ips

looks like your linksys  router don't support multiple public ips so try the half bridge mode .  you will loose the ability to use the wireless. In fact your linkys will work as just a modem to your   fortigate but then very easy to manage.

It's call bridge mode in your router user guide page 9 (have a look at the end of the page 9)

the problem is that my FG is not able to create PPPOA connection (only PPPOE).
And so it won't be possible for me to work wihout NAT and DMZ.
It used to work with the DMZ and I don't know why it's not working anymore...
