Hi Matt, Check out this post and config: https://blog.voipxswitch.com/2016/08/11/kamailio-and-freeswitch-on-the-same-...
It demonstrates how to handle NAT & forward a REGISTER to FreeSWITCH (on localhost) Thanks, Emmanuel

I have configured Kamailio to pass a registration request to another VoIP provider. The reason I am doing this is to provide a sip port for users where the ISP is blocking SIP. I am able to pass the registrations to

the
inbound invites coming into the Kamailio server but it appears that the server does not 'know' about the UA that is registered 'through' the
server
to the VoIP provider. Can anyone tell me how to fix this problem?
Below is
my config.
You should look into the NAT handling tricks: http://www.kamailio.org/docs/modules/stable/modules/ nathelper.html#nathelper.set_contact_alias and http://kamailio.org/docs/modules/stable/modules/ nathelper.html#nathelper.f.handle_ruri_alias
Take a look at the default config NATMANAGE routes and enable "natting" for all sources except you upstream server.
Alternatively if the registrar of the voip provider supports Path, enable that in kamailio use http://kamailio.org/docs/modules/stable/modules/path.html#idp38122172 in the registers to add the header and set http://kamailio.org/docs/modules/stable/modules/path.html#idp38033932 to handle the INVITEs
