Re: [asterisk-users] SPA-2102 sending local IP instead of WAN IP in SIP packets

This is what frustrates me that it's not so straight forward to Asterisk to obtain the proper public IP of the device from the IP packet headers rather than the SIP packets. 'nat=yes on the device' doesn't really make any sense; does that mean you set some sort of NAT setting on the *device* itself, or does it mean you set 'nat=yes' in the device's peer entry in the Asterisk sip.conf file? If 'nat=yes' is set in the relevant sip.conf peer entry for that device, and Asterisk is properly selecting that entry when the device registers, then Asterisk *will* respond the device's apparent IP address and port number, regardless of the address the device includes in the Contact header of the REGISTER request. Setting 'nat=yes' is exactly how you tell Asterisk to use the IP address from the IP header of the packet instead of the address in the SIP message. As I said before, there are likely hundreds of thousands (if not millions) of endpoints registering to Asterisk systems all over the world every day using this mechanism and it works just fine. If it's not working for you, there is some sort of configuration problem. -- Kevin P.

Thanks when you do a sip debug do you see something like this: SIP read from 192.168.0.2 for example or do you see the internal ip only in the contact header? if its only in the contact header everything is ok. if not you maybe have a network problem like SIP ALG on your router. Asterisk can only work with the data which are received. turning NAT on or off only switch between the IP in the contact header or the source IP but if your device in between like a router does something wrong like faking packet source ips asterisk cant fix this. i dont know what kind of router you use, but have a look at SIP ALG and turn this off, if possible. best regards stefan -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
