[Pound Mailing List] setting up pound listeners for dual stack IPv4 and IPv6`

[Chris Harrison]

hello All,
I hope this list can help me.

I have had difficulty finding any references to setting up pound with 
IPv6 especially in a dual stack environment.
I already have a Heartbeat supported IPv4 Pound installation.  I have a 
listener on port 80 that redirects to the ssl version on port 443.  from 
there haproxy listens to 127.0.0.1 and load balances between IPv4 web 
servers.  I want to have the same ports on the IPv6 address do they same 
thing.  if i remove the IPv6 listeners the IPv4 work.  if I add the IPv6 
listeners i get
I think that they should look like this (actual data hidden):
/etc/pound.cfg
#pre-existing and working

#servername -IPv4 listener
ListenHTTP
    Address xxx.xxx.xxx.20
    port    80
    xhttp   2
    Service
        Redirect    "https://servername";
    End
End

#servername - ssl
ListenHTTPS
        Address xxx.xxx.xxx.20
        Port 443
        Cert "/etc/servername.pem"
        Service
                BackEnd
                        Address 127.0.0.127
                        Port 80
                End
        End
End

#how I think the the IPv6 should look but doesn't work

#servername -ipv6 listener
ListenHTTP
    Address yyyy:yyyy:yyyyy:yyyyy::20
    port    80
    xhttp   2
    Service
        Redirect    "https://servername";
    End
End

#servername - IPv6 -ssl
ListenHTTPS
        Address yyyy:yyyy:yyyy:yyyy::20
        Port 443
        Cert "/etc/servername.pem"
        Service
                BackEnd
                        Address 127.0.0.127
                        Port 80
                End
        End
End

127.0.0.127:80 is the HAproxy load balancer to the back end IPv4 web 
servers.

Any suggestions about what i am missing?
Thanks
