Hi Marko,

Depending on your version of netstat it may be truncating the IPv6 address. Try using `ss -n -6 state listening` and see what it reports.

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
