Tranzeo / PPPoe / Mikrotik

I am having a problem with getting a client to connect via PPPoE. I have 3 other clients with same setups. My radius server says no password, Mikrotik says radius timeout or auth fail. If I put the username/pass in Mikrotik PPP Secret it works fine. So it seems that the MT is not sending the password info to my radius server for this particular connection. Any ideas?

Give more details:
PAP / CHAP. What radius server, what PPPoE Client?

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.
