[SR-Users] Kamailio not listening to proper ipv6 address

[Michael Young]

Marko,

 

In our network, we have it working with this listen line:

 

listen = [2600:1234:7522:abcd::aaaa:bbbb]:5060

 

which is slightly different from what you have below. We are listening on both udp and tcp. I don’t know if that will help you or not – but they key take away may be that it does work. We are running version 5.0.

 

I am assuming the address is not really yyyy:xxxx as that would not be a valid IPv6 address. But you are probably just obfuscating that.

Hi,

I need to enable Kamailio to work with ipv6 also, and I enabled 

auto_bind_ipv6=1

and when restarted I can see that it is listening to ipv6 ip addresses also.

The problem is that it stripped the ip address at the end and it is listening to the wrong one.

When I try to register I get timeout, since it is not listening the correct address.

ip address of the server is 2604:a880:400:d0::yyyy:xxxx

and when I execute "sudo netstat -plnt" too see which app is listening to which address/port I can see:
....

tcp6       0      0 2604:a880:400:d0:::5085 :::*                    LISTEN      17748/kamailio
tcp6       0      0 2604:a880:400:d0:::5061 :::*                    LISTEN      17748/kamailio

It somehow stripped the last part of the address (yyyy:xxxx). I dont know if it is related to :: which would be all zeros, but it doesn't work even if i explicitly specify which address to listen with

listen=[2604:a880:400:d0:0000:0000:yyyy:xxxx]
or
listen=tcp:[2604:a880:400:d0:0000:0000:yyyy:xxxx]:5061

or
listen=tcp:[2604:a880:400:d0::yyyy:xxxx]:5061

 

I tried all combinations and the results are always the same...

Have anybody had this problem before?

Do you know how to fix this?

 

Best regards,

Marko Selakovic
