This is the only connection I established (I just started). Really weird is: when I turn of the  sendmail on the real server and a packet is send from the real server with the AR flag set it gets through the virtual server and I get a connection refused on the client.
The checksum problem only seem to occur with the SA flag on.
Direct connections from the virtual server to real server on the smtp port is working too.
And when I use iptables -j DNAT to real server sendmail is answering correctly.
