pptpclient don't work with MPD

[Paul]

Hello, All.

I use MPD as VPN-server under FreeBSD 4.7.
When VPN client runs under windows(2000, XP) all right,
when VPN client is MPD and runs under FreeBSD all right too,
when VPN client is pptpclient from ports collection and runs under FreeBSD,
connection between MPD-server and pptpclient successfully stands up, but DON'T WORK.
i.e. when i try to ping another end of VPN-connection i get next logs:

VPN-server machine, mpd.log:
    Jun  9 14:07:35 vpnserver mpd: [pptp] rec'd unexpected protocol 0x8e3b on link -1, rejecting
    Jun  9 14:07:36 vpnserver mpd: [pptp] rec'd unexpected protocol 0x0047 on link -1, rejecting
    Jun  9 14:07:37 vpnserver mpd: [pptp] rec'd unexpected protocol 0x006d on link -1, rejecting

VPN-client machine, ppp.log

    Jun  9 14:03:07 vpnclient ppp[90176]: tun0: LCP: deflink: -- Protocol 0x006d (unrecognised protocol) was rejected!

When i use PoPToP as VPN-server and MPD as VPN-client i get analogious results...

If somebody could connect MPD and pptpclient help me please.
