IPv6 redirect Support? #10

Closed azure9 closed 3 years ago

azure9 commented 5 years ago

Do you have plan support ipv6 proxy?

hmgle commented 5 years ago

It does support IPv6. This line: https://github.com/hmgle/graftcp/blob/db56ea4a31359d8b9adcd57b24f1feadb5ed6a83/graftcp-local/local.go#L178

will call net.Dial that support IPv6.

But if your local network or ISP does not support IPv6, the remote IPv6 proxy is unable to be reached.

Seems the graftcp part not hijack ipv6 flow, e.g. you can setup a shadowsocks server using shadowsocks-libev, and the flow won't be redirect by graftcp while at same time IPv4 works fine.

Oh, I see. This line https://github.com/hmgle/graftcp/blob/db56ea4a31359d8b9adcd57b24f1feadb5ed6a83/graftcp.h#L40 s_addr is IPv4 only. Thank you for your feedback.

IPv4/IPv6 dual-stack feature is under development on the ipv6 branch.
