SetUp Details :-
IpV4 ethernet cable is connected to MAC machine. Now as per apple documentation steps are followed. Where DNS64/NAT64 is created and hotspot is created.
Device is connected to wi-fi which is created by hotspot on mac machine.
Application status :-
My application is Push to talk (PTT) application. Now i have launched the application where i am establishing to connection to my server.
1) SIP Connection :- FQDN is provided to DNS64/NAT64 which mapped to ipv4 address. so DNS64/NAT64 gave me synthesised ipv6 address. Here TCP connection established successfully.
2) MEDIA Connection :- ipv6 address [Direct server ip] application has given to DNS64/NAT64 but TCP connect is failing as client is sending SYN but "route unreachable error is received".
3) From the browser of device , I am trying to open only ipv6 supported website but it showing "server could not found". But ipv4 and ipv6 both supported website is opening as it's taking ipv4 route.
Please provide a solution how to reach ipv6 address through DNS64/NAT64 network.
