 Установил мпд на Freebsd 5.4 на HP DL140g2.
 Hастроил мпд на 800 клиентов, 700 pptp и 100
 pppoe.
 Клиенты в принципе работают, но через
 какое-то время впн у них встает колом.
 При этом через ng* пакеты проходят,
 запросы ответы, по несколько байт, но
 нормально не работает ничего.
 При этом в логах (mpd.log) появляется:
 May  5 19:06:14 access mpd: [vpn0] IFACE: Up event

 Иногда в messages появляется такие строки:
 kernel: ng_mppc_decompress: too many (4094) packets dropped, disabling
 node 0xc74a2e0  , до пересборки ядра с options
 NO_ADAPTIVE_MUTEXES, их было больше гораздо.
