Trying to configure IPv6 over PPPoA on ADSL PIM in ScreenOS 6.3.0r11 on SSG20.
ISP provide both IPv4 and IPv6 over PPPoA.
While IPv4 works as expected I can't get IPv6 to work. There doesn't seems to be any IPv6CP support on PPPoA (the option exist in PPP and PPPoE profiles to change IPCP/IPv6CP order but not on PPPoA).
Just enabling DHCPv6 client doesn't work, I can see (in log) the request going out of adsl1/0 but, of course, nothing comming back. I would expect the address to be received part of the IPv6CP negotion under PPPoA.
ISP is Andrew & Arnold (UK).
Did anybody had more luck than me? Any workaround/recommendation? (switching to PPPoE is not an option).
