[SOLVED] X Server not accepting remote connections after update

Question

Hi everyone! After recent upgrade Xorg on my laptop not allows other machines to use him as a window server, just an example:
on laptop:
vitaly@trifon:~/VM$ ps aux | grep Xorg
root       499  2.7  1.3 393628 105276 tty7    Ssl+ фев17 139:48 /usr/lib/xorg-server/Xorg -br -novtswitch -quiet :0 vt7 -auth /var/run/xauth/A:0-rfwYma
vitaly   23338  0.0  0.0  10728  2272 pts/3    S+   08:01   0:00 grep --color=auto Xorg
As you can see, '-nolisten tcp' flag is absent.
vitaly@trifon:~/VM$ xhost
access control enabled, only authorized clients can connect
INET:192.168.2.2
INET:192.168.13.13
192.168.2.2 is my Virtual machine, which works perfectly before upgrade
if I try to start some graphics program, I see that:
[sandbox@sandbox ~]$ DISPLAY=192.168.2.1:0.0 xterm
xterm: Xt error: Can't open display: 192.168.2.1:0.0
Please tell me how can I let my server work?

No good results
first i scanned 6000 port, it was closed. i scanned random ports, all was "closed" too

But scan result on working machine tells me that 6000 port is open (Debian Wheezy, dist-upgrade done yesterday, xorg-server was updated and restarted)
