PPPOE won't establish when previously worked on a Cisco 887

[engineer_rpt]

I can't get PPPOE to establish it just sticks at initialising when going between a 40F and a Virgin Small Business Hub (UK ISP).

It works fine with Cisco (config below) but won't come up with my FortiGate. One thing I've seen is that the Cisco was set specifically to CHAP. So I'll try that next time but wondering if anyone has had any first experience with this issue?

Relevant Cisco Config (identifying info. scrubbed):

interface FastEthernet3
 description Virgin Media cable circuit ref: REFERENCE
 no ip address
!
interface Virtual-PPP1
 description Virgin Media circuit ref: REFERENCE

 ip address negotiated
