I have tried both PAP and CHAP. The first client was a motorola router, now the same problem with a linksys router. The radius server is VOP Radius by Vircom. It seems the info is getting passed to the MT box since putting the same login credentials in the MT works. It's most confusing as I already have 2 pppoe clients working. Pretty sure they are linksys, will double check.Give more details:
PAP / CHAP. What radius server, what PPPoE Client?
