Hi

I need help on NAT with Kamailio...

My Network Details are as follows...

SIP Phone Registration                                                          ADSL Router                  Kamailio                                      Asterisk

172.18.100.73/255.255.0.0                                                   192.168.1.1/255.255.255.0                        192.168.1.68/255.255.255.0        192.168.1.70/255.255.255.0
172.18.100.72/255.255.0.0 GW: 172.18.100.72                                    (Virtual IP 172.18.100.68)            (Virtual IP 172.18.100.70)

Router Type: AirLink 101 802.11 Token Ring

Where Virtual IP 172.18.100.68 and 172.18.100.70 set virtually on ADSL Router.. and set routing on it..

So when I ping 172.18.100.70 it will go through 192.168.1.1

I am able to call, receive means able to receive OK, INVITE and REGISTER method of kamailio ... but When i try to Hangup call, it can't hangup at both side..
I have to manually cut phone at the other end..

I have not set any rule on Router.

Scenario...

1] I have two user. 1212@domain.com [172.18.100.73] and 2121@domain.com [172.18.100.72] and register successfully
2] Call from 1212@domain.com [172.18.100.73] to 2121@domain.com [172.18.100.72]..
3] Call is connected successfully
4] While hangup from 1212@domain.com [172.18.100.73] it will take time and at the other end, I have to manually hangup call..

Please help me out..
