Stefan, If I understand you correctly, your main Asterisk server via AstLinux has a dynamic IPv4 on the external interface.
I have not needed to try this, but on the "client end" (assuming AstLinux/Asterisk again) take a look at the asterisk dnsmgr.conf entries, and set "enable=yes" and see if that helps. Depending on the TTL of the dynamic DNS entry, you will have a period of time when things won't work. Clearly a static IP at the server end is the "production" method. Possibly you can obtain a static IPv6 address at the server end and IPv6 connectivity at the client ?
