Between slirp and the outside world only 'normal' host's sockets are used. Anyway, as a 1st step I will transform taprouter into an easy-to-link module. Then, I will look how to integrate it into DOSemu. cheers Mateusz ebiederm@xmission.com wrote: >Mateusz Viste writes: > >> Hi >> >> I do not think there is any ipv6 support in slirp.
