British Telecom (for example) offer a static IP service which works by assigning a dynamic link address to the PPP endpoint (The firewall in this case) and then the exchange equipment routes the blocks of static IP addresses to this device based on their dynamic link address.
On a cisco device, all you have to do is unnumber one of these static addresses against the dialer interface and you can assign a static to the firewall/appliance.
This never seems to work in FortiOS - the system seems to ignore the unnumbered address, amd I always have to use DDNS to enable the use of SSL VPN etc. Is this expected behaviour ?
I want to recreate this: (Vlan 1 has one of the assigned statics)
ip unnumbered vlan1
dialer pool 1
ppp authentication chap pap callin
ppp chap hostname BROADBAND USERNAME
ppp chap password BROADBAND PASSWORD
ppp pap sent-username BROADBAND USERNAMEm password BROADBAND PASSWORD
Not sure what you men ignored, but did you remove all policies or other bindings under wan1? PPPoE is straight forward but if you re reconfiguration from a mode other-than pppoe, than you need to police any dependencies checks.
