Thanks. I finally figured it out by myself. Sorry for posting early.

I have another problem though.

When I connect to VPN, user and password are verified and radius says 
their are ok. After that VPN client registers me on the network (gets 
IP address and so on). But in the middle of registration something 
happens and I get disconnected. There are no errors in Radius server 
log. However there are some in VPN server's:

Connect: ppp0 <--> /dev/ttyp0
MSCHAP-v2 peer authentication succeeded for admin
found interface eth0 for proxy arp
local IP address 10.1.1.1
remote IP address 10.1.1.202
executing firewall rules
signal SIGUSR1 received - rebuilding portmappings
RADIUS: server 213.190.40.42 not responding
RADIUS: server 213.190.40.42 not responding

Is is because of some strange external/internal IP problems? What 
Radius server must do after I authenticate?
