*Dear Sir,*
I have opened an issue on GitHub: *"IPv6 bind wrong IP. #4199 https://github.com/kamailio/kamailio/issues/4199"*.
*System Details:*
-
*Kamailio (5.8.x)* – SIP Proxy -
*FreeSWITCH* – Media Server -
*OS* – Debian 12 -
*Gateway* – aaaa:bbb:cccc:20::1 -
*IPv6 Address* – aaaa:bbb:cccc:20::41e
------------------------------
*kamailio.cfg:*
#!define ADDR_IPV4 xxx.xxx.xxx.xxx #!define ADDR_IPV6 [aaaa:bbb:cccc:20::41e]
listen=ADDR_IPV4 listen=ADDR_IPV6
------------------------------
*netstat Output:*
tcp6 0 0 aaaa:bbb:cccc:20:::5060 :::* LISTEN 1691274/kamailio tcp6 0 0 aaaa:bbb:cccc:20:::5061 :::* LISTEN 1691274/kamailio udp6 0 0 aaaa:bbb:cccc:20:::5060 :::* 1691222/kamailio
As shown, although I explicitly set the listen IP to aaaa:bbb:cccc:20::41e, Kamailio strips the last part of the address and binds to aaaa:bbb:cccc:20::
I also upgraded to *version 6.0* with default cfg and set auto_bind_ipv6=1 or changed ipv6 address, but the issue still persists. ------------------------------
*IPv6 Interface Configuration:*
auto eth1 iface eth1 inet6 static address aaaa:bbb:cccc:20::41e netmask 64 gateway aaaa:bbb:cccc:20::1
I can successfully ping in and out using this IPv6 address. ------------------------------
Do I need to configure anything else in Kamailio or the system to ensure it binds to the full IPv6 address aaaa:bbb:cccc:20::41e as expected?
Currently I can register with ipv4, but ipv6 does not.
Thank you for your assistance.
