>Description:
After a pptp connection with mpd port, I found very serious packet lost.
I hope it was caused by a misconfiguration of mpd port.

mpd.conf:
---------------------------
default:
        load pptp0
pptp0:
        new -i ng0 pptp0 pptp0
        set ipcp ranges 172.16.1.254/32 172.16.1.100/32
        load pptp_standard
pptp_standard:
        set iface disable on-demand
        set iface enable proxy-arp
        set iface idle 1800
        set iface enable tcpmssfix
        set bundle enable multilink
        set link yes acfcomp protocomp
        set link no pap chap
        set link enable chap
        set link keep-alive 10 60
        #set link mtu 1460
        set ipcp yes vjcomp
        set ipcp dns 213.244.0.15
        set ipcp nbns 172.16.1.4
        set bundle enable compression
        set ccp yes mppc
        #set ccp yes mpp-e40
        set ccp no mpp-e40
        set ccp yes mpp-e128
        set ccp yes mpp-stateless
>How-To-Repeat:
install mpd under FreeBSD 5.3 RC1 (src/sys updated to Oct 20 stable)

   Li,
 
 can you show us ping to peers address? It is important to see whether 
 there is any PL or latency deviation.
 Do you know which software is used for PPTP on remote side?
 
 Archie, any ideas?

 Not without more information..
 
 You could try 'set pptp disable windowing' to see if that helps.
 Also, you might ask on the mpd-users@lists.sourceforge.net list.

That typical problem of the enabled PPTP windowing. 
It is recommended to disable it to fix it. 
There was also related commit to ng_pptpgre.c merged 
to RELENG_6 last time.
