Hello,
My suggestion is that stay away from NAT if you dont have to. various sip
client/Firewalls make out troubles for registration and invites, even if
Kamailio can handle it. If you have a high load TLS connection / subscriber ,
I think you should use load balancer and NAT options.
For example;
1 - Load balancer like F5 that balancing your connection active-active
Kamailios
UAC ----> F5 ------> Kamailio -1 (advertises public IP)
|
-------> Kamailio -2 (advertises public IP)
2- Use kamailio as MultiHomed that convert transport layer to tcp/udp
UAC ---------> Kamailio(TLS-PUBLIC IP-mhomed) -------> Kamailio-1(TCP/UDP)
|
---------> Kamailio-2(TCP/UDP)
Good luck
Yasin CANER

Subject: [SR-Users] Kamailio behind NAT or With Public IP - Which one is highly
recommended
Hi Everyone,
Which one among the below option is highly recommended for setting up Kamailio
(for production)
1. Kamailio behind NAT or
2. Setting up Kamailio using public IP?
are there any disadvantages if we setup Kamailio behind NAT and use advertise
option in listen parameters?
We have tested both the options, and both the options work great for us( a.
Kamailio behind NAT with advertising in listen parameters b.Kamailio setup with
public IP). So wondering which one is best and highly recommended?
Some extra info :
1. We use TLS
2. Using coturn for media
Thanks
Pintu
