Grandstream gxp1610 always replace inner ip address to public


#1

Hello everyone. Please tell me why i get public address from my phone connected over vpn?
Phone settings -> NAT Traversal NO ( phone show nat status - unknown nat ).

I have 2 networks 192.168.0.0/24 and 192.168.30.0/27 connected over openvpn 192.168.8.0/24
All devices from 192.168.30.0/27 work over vpn exept grandstream phones. I sure i dont have any problem with routes or networks, because i tested it with tcpdump and telnet ( all devices connected with inner ip’s)
I think phone has special settings which replace inner address to public, but i discouraged which one.
