Hey Radu,

your mentioned SNI-Relay logic is indeed a cool method to support Piotrs requirement without switching between multiple different Server_SSL_Profiles. Great hint and Kudo +1...;-)

 

when CLIENTSSL_HANDSHAKE {
    if { [SSL::extensions exists -type 0] } then {
        set tls_sni_extension [SSL::extensions -type 0]
    }
}
when SERVERSSL_CLIENTHELLO_SEND {
    if { [info exists tls_sni_extension] } then {
        SSL::extensions insert $tls_sni_extension
    }
}

 

Cheers, Kai
