Hi all, TL,DR: I am working on QEMU ipv6 guestfwd feature and finished coding, and would like to learn the best practice to test it. Context: in slirp side this task is tracking by [1]. Currently, I have done following: i. made char parse + guestfwd functions happy with ipv6 address. ii. enabled debug print and made sure the ip and port are inserted into the forward list in libslirp. To sufficiently verify it's working, I do have three questions: 1. I want to forward a port in the guest (OS in QEMU) to a port 22 on the host OS, and ssh from guest back to host, does this sound reasonable? If this is not a good idea, what method is recommended? 2. I want to understand what ip I should use. Currently I have following formats for the QEMU invocation in ipv6: ``` guestfwd=tcp:[::1]:1234-tcp:[my:host:ip:from:ifconfig]:22 ``` I know the general form is `guestfwd=tcp:server:port-dev`, where server:port is for guest, dev is for host. Adding [] in my implementation will let QEMU know it's ipv6. Is the aforementioned invocation correct? Or in this case [::1] is the local host address and I should put qemu address for it instead? 3. Is there a default ipv6 address for QEMU instance? I think I need it in the invocation.
Thanks in advance! Felix [1]. https://gitlab.freedesktop.org/slirp/libslirp/-/issues/67
