UTM 9 - ipv6 NAT with proxy POP3 enabled

Daniel Huhardeaux

Hi,

after having setup succesfully ipv6 behind the UTM9, I face a problem with POP3 when proxy mode is enabled. I have my own server in DC running Dovecot, desktop client behind UTM has his own ipv6 and is running Thunderbird.

When I want to fetch mails, Thunderbird tells "Fetching message 1 of x" and after a while finish in timeout. On the server, netstat -tapen|grep 110 show that the ipv6 address which is fetching mails is the one of external ipv6 interace, which means NAT is done ! If I disable proxy POP3, all is good.

Does this behavior seems normal to you?

Daniel

    No one ?

    I have to mention that enabling the proxy POP3 and adding "all ipv6" in advanced -> transparent excluded is working too. If I telnet port 110 and ipv6 is removed from transparent excluded, I have:

    USER <my user>
    OK
    PASS <my pass>
    OK
    list
    1
    .
    X
    OK
    RETR 1
    !!! Timeout occur !!!
