FreeBSD+mpd freeze after connection establishing

[Alexey A. Ukhov]

also want to add:

it looks that system itself works if gateway was not changed.
Example - after connecting I have new interface ng0, but old gateway

# ifconfig ng0
ng0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 
mtu 1460
        inet 10.10.1.201 --> 10.10.1.100 netmask 0xffffffff

As only I assign 10.10.1.100 as defaul gateway system freeze after first 
packet.
