Hi I've tried you HTTPS-and-HTTP.ino excample and it works fine for IPv4.
Currently I'm trying to use IPv6 instead.
I have configured the WIFI to get an IPv6 addres which works fine I can ping the address.
then I have changed your code of HTTPServer to use IPV6 sockets.
uint8_t HTTPServer::setupSocket() {
// (AF_INET = IPv4, SOCK_STREAM = TCP)
_socket = socket(AF_INET6, SOCK_STREAM, IPPROTO_IPV6);
if (_socket>=0) {
_sock_addr.sin6_family = AF_INET6;
// Listen on all interfaces
struct in6_addr lo6 = IN6ADDR_LOOPBACK_INIT;
_sock_addr.sin6_addr = lo6 ;
Serial.println("_bindAddress");
// Set the server port
_sock_addr.sin6_port = htons(_port);
// Now bind the TCP socket we did create above to the socket address we specified
// (The TCP-socket now listens on 0.0.0.0:port)
int err = bind(_socket, (struct sockaddr* )&_sock_addr, sizeof(_sock_addr));
#if LWIP_IPV6
Serial.println("ipv6");
#endif /* LWIP_IPV6 */But connecting with curl to the IPv6 address i'm getting a connection refused.
When the ESP32 is not running I'm getting timeouts for ping and curl. If I try curl with IPv4 I get the expected output.
Any hints where I have to look in the code for IPv6 support?
Regards
Matthias
