Hi, I have a problem with a vpn setup, not really nat, or maybe it's nat...
The setup I have is: Phone - openvpn - opensips - public internet - asterisk openvpn subnet: 10.0.0.0/24 openvpn server: 172.172.0.2/24 opensips server: 172.172.0.10/24 In my configuration I have: loadmodule "mid_registrar.so" modparam("mid_registrar", "max_contacts", 1) modparam("mid_registrar", "mode", 0) modparam("mid_registrar", "received_avp", "$avp(rcv)") modparam("mid_registrar", "tcp_persistent_flag", "TCP_PERSIST_REGISTRATIONS") if (nat_uac_test(119)) { setbflag("NAT"); if (is_method("REGISTER")) { fix_nated_register(); } else { fix_nated_contact(); } } if (is_method("REGISTER")) { mid_registrar_save("location", "p0"); ..... } if ($(tu{uri.param,ctid}) != NULL && mid_registrar_lookup("location")) { if (!t_relay()) { send_reply(500, "Internal Error"); } } So, when the phone sends a REGISTER to opensips, the contact header contains the private ip of the vpn (10.0.0.X/24). fix_nated_register is able to detect that the ip in the contact is different from the source ip and sets the received avp. But if I do opensips-cli -x mi ul_dump, I see that the contact still contains the openvpn ip, and the received field contains the correct openvpn ip. This is a problem because when I do the mid_registrar_lookup, $ru is set to the contact, which contains an ip that the opensips server is not aware of. It should instead contain the openvpn server ip (172.172.0.2), that could then route the call to the phone. I tried to change $rd manually, but that just breaks routing for ACK messages. What am I doing wrong? Thanks
