Ipv6 only issue

[bainbin]

I'm trying the proxy when only Ipv6 is enabled on LAN.
explicit end point created with IPAddress.IPv6Loopback & proxy is set as system proxy.
The requests are intercepted, but no site is reachable.
Not ivp6 only sites nor ipv6-test.com like ..

similar issue here... v6 only sites fail with a could not establish connection error

Test Url: http://v6.testmyipv6.com/

I think the issue is with local address binding

ok so local address issue solved by using 2 explicit endpoints, one for v4 and one for v6 both on the same port. so now i can talk to the proxy using both 4 and 6 but calls dont go out over 6 only 4. This is my curl.

• V6: curl -k -6 -x [::1]:44444 https://v6.testmyipv6.com/

• V4: curl -k -6 -x [::1]:44444 https://v4.testmyipv6.com/

• Dual: curl -k -6 -x [::1]:44444 https://ds.testmyipv6.com/

all responses show only v4 requests out of the proxy...

and yes curl -k -6 https://v6.testmyipv6.com/ works

ok so it looks like after it does the dns resolution it then tries the available ip addresses. The issue here is that the tcp client has already been made and defaults to address family for v4 when in fact this can not be known until we are ready to try the connection.

@justcoding121 ^bug?

I'll check it in the weekend.

[ByronAP]

ty here is where the connection is attempted but will fail https://github.com/justcoding121/Titanium-Web-Proxy/blob/master/src/Titanium.Web.Proxy/Network/Tcp/TcpConnectionFactory.cs#L315

I worked around it by moving the tcpclient creation inside the loop (with some added cleanup if it fails). I would do a PR but my code is on .net v3 which fixes the socket reuse issue and allowed me to make a bunch of other changes.

Please try the latest beta build (will be released in some minutes)
