HAproxy : translation of public IPv6 adresses and private IPv4 addresses

[OOWORX .com]

Hi all, 

 

Concerning HAproxy with translation of IPv6 and IPv4 addresses, 

 

This configuration is functional : 
listen  ipv6proxy80     2607:f208:1:1000::101:80
        mode    tcp
        server  ipv4server80    192.168.0.2:80
        maxconn 4000

 

This one is not functional :
listen  ipv6proxy80     2607:f208:1:1000::101:80
        mode    http
        server  ipv4server80    192.168.0.2:80
        maxconn 4000

 

Difference is between tcp and http mode. 

Is it a normal behaviour ?

 

Thanks for your answers.
