Стоит FreeBSD 5.3 + mpd 3.18 + freeradius 1.0.1
При эксплуатации этой связки возникли следующие вопросы:
1. К mpd подключают ethernet клиенты, получают внешние ip адреса и выходят в инет. Однако присутсвует одна проблема - постоянно происходит разрыв связи с клиентом. в логах mpd появляются следующие надписи:

Связь может рваться каждых 3-10 минут.
2. Когда я включаю шифрование и компресию в настройках mpd, то у клиентов, у которых стоит WinXP устанвливается mtu 1398, работают плохо, инет открывается не весь. Как с этим побороться?
Конфиги mpd:
mpd.conf:
pptp49:
new -i ng49 pptp49 pptp49
set ipcp ranges 10.0.0.50/32 x.x.x.x/32
load pptp_standart
pptp_standart:
set radius server 127.0.0.1 xxxx 1812 1813
set radius timeout 10
set radius config /etc/radius.conf

set bundle enable multilink
set bundle disable compression
set bundle enable radius-auth
