Hi Oliver,

Thanks for your reply. I do not block any out going tcp or udp traffic
as this machine is used only by myself. For that I have the following

$fwcmd add 00303 allow tcp from any to any out setup keep-state

$fwcmd add 00405 allow udp from any to any out

Do you think the setup keep-state could be causing a problem? Thanks for
making the point on my subnet, I have changed that accordingly.

Kind regards,

ps. I am not subscribed to the list so please send answers to me

the server initiate the connection from the port 20.
