mpd as VPN-client in FreeBSD

[baguio_sun at ms.tusur.ru]

Hi!
I'm using mpd (as client)to connect to VPN-server. When I don't use mpd, my
default route is 192.168.1.1. Then when i'm connected to the VPN-server, i
have a new iface ng0 with ip 212.192.123.86. But default route is still
192.168.1.1! And I have to '# route change default 212.192.123.193'
manually .
The question : is there a line in mpd config files, that sets the new route
automatically (after sucsessfull connection)?
I've read the f*****g manuals(both man and html files), but didn't find
anything useful for me.
Please help me !
Thanks for your time.
