Hello I have a problem with stunnel : I just don't know how to specify 2 different port forwarding, one for all ipv4 connections to port 443, the other for all ipv6 connections. Either one seem to work, but I can't have both at the same time. In my /etc/hosts : 127.0.0.1 localhost ::1 localhost6 0.0.0.0 listenall4 :: listenall6 In my stunnel.conf: [sslh] accept = listenall4:443 connect = 127.0.0.1:444 TIMEOUTclose = 0 [ssl6] accept = listenall6:443 connect = 6.guylhem.org:80 TIMEOUTclose = 0 I have read that linux can block ipv6 sockets if the ipv4 socket is created first, but here the order doesn't change anything. I though that stunnel was ipv6 capable, but apparently it doesn't play well with ipv4 on the same port. So I tried to remove one of the listenall : the listenall4 is important, but listenall6 is not. Yet giving a AAAA only host like 6.guylhem.org does not help - even if it goes before the listenall4. So I'm stuck. Has anyone patched stunnel for such a situation? Guylhem
