  1. KAZOO server behind NAT

    in Product Discussion

    Posted · Edited by Rhys (see edit history)

    @naveed6865 Yeh I have set up an elastic IP for Kamailio and Kamailio is bound to private IP but advertising the elastic IP ie:

    listen=udp:a.a.a.a:5060 advertise x.x.x.x:5060     ##a.a.a.a is your private IP address    x.x.x.x is the external IP address

    I then configure the modparam to enable the double RR setting, but at this point I get two RR both containing the elastic IP.  

    For aliasing are you suggesting I set up a vip of the elastic IP on an alias interface ie eth0:0?? OR Alias in kamailio config ie alias=xxx.xxx.xxx.xxx??

    Its worth noting I only have a single nic.

    you can enable double record route in kamailio, so kamailio will put both public and private ips, but actual communication will be on private ips between freeswitch and kamailio, 

    Hi Naveed,

    When enabling dourble record routing (setting 'modparam("rr", "enable_double_rr", 2)') in kamailio config.... kamalio will insert the advertised sip address in both headers - which in my case is the AWS Elastic IP/NAT IP.

    Is it possible to tell kamailio to advertise both the Public/NAT IP and Private IP in the two RR headers? 

    Cheers

    Hi,

    I have Kazoo set up in aws providing the public IP address for NAT and kamailio bound to the private IP - as per https://forums.2600hz.com/forums/topic/11827-kazoo-in-azure-is-it-supporteddoes-it-work/?tab=comments#comment-61838

    The issue I am having is that for any SIP Request (e.g INVITE).... KAMAILIO is inserting a record route of the public IP, regardless of whether the message is routing to a freeswitch box within AWS (bound on private IP) or externally to a sip device.

    Is there anyway to set up Kamailio to NOT advertise the public IP (in RR header) if connecting to a freeswitch box bound on a private IP and ONLY advertise a public IP (in RR) if routing outside of the private IP subnet.

    Many Thanks,
    Rhys
