Проблема с radius.so

[Aug]

Настроил pptpd-1.3.0 + pppd-2.4.3 под Linux RH AS4 (2.6.13), если без radius авторизация, а через файл chap-secrets - то все работает и подключается... только указываю plugin raduis.so - пишет у VPN-клиента под виндой Ошибка 737: Обнаружено замыкание на себя. В чем может быть причина? UTM4+NetUpRADIUS
Лог pptpd и pppd:

Эта проблема решилась, но radiusclient не цепляется к серверу
в логе пишет

RADIUS-сервер (NetUP из UTM4) запросов не обнаруживает... файрвол выключен, в чем могут быть грабли?

Скорее всего несоответствие PPP И PPTPD. У меня решилась проблема игрой разных версий

Эта проблема решилась, но radiusclient не цепляется

Опишите, как именно решилась, пожалуйста! Очень интересует этот вопрос...
