USE adsl modem as a bridge

Experts,
I’ve dlink DSL-500T, i wanna use it as a bridge and dial from my mikrotik, i use v 5.20
my isp use PPPoA, not PPPoE
i found this link

but didn’t work with my , i think the issue is that the ISP use PPPoA not PPPoE, and the mikrotik not have PPPoA client

Take a look at this blog entry http://robert.penz.name/484/howto-use-a-mikrotik-as-router-for-a-pppoa-dsl-internet-connection/ … Different modem but also mikrotik router
