Проблема с mpd4 на freeBSD 6.1
Запускаю mpd4 (самый свежий из портов), связь устанавливается, но если начинаю пинговать vpn сервер, то в логах появляются ошибки и хост не отвечает на пинги. Если я устанавливаю это же соединение под виндой, то хост пингуется без проблем.

если не поможет - поставь мпд-3 (который просто MPD)

и ещё попробуй после запуска MPD выполнить
route delete 0.0.0.0
route delete default
route add 0.0.0.0 <айпи, КОТОРЫЙ ПРИСВОИЛ MPD> (например у меня локальный 10.0.1.8), а когда врубаю инет - становится 192.168.1.8
route add default
