Did it. Nothing happens. Brwoser says "timeout" and manually retrieving the
site gives no output on the client. In tcpdump on the client side (!) I see
the following:
Client -> Server: GET / HTTP/1.0
Server -> Client: Seq=1 Ack=17
Client -> Server: HTTP Cont "\r\n"
Server -> Client: Seq=1 Ack=19
Server -> Client: HTTP "Contents of the page"
Server -> Client: HTTP Cont "Contents of the page", 3 times
(After one sec)
Server -> Client: HTTP TCP retransmission, going on.
It seems the the data is not received by the client and not ACK are sent by
the client. This is kind of strange, since this tcpdump is gathered from the
network interface from the client.

Timeout.

TCP Syn, Syn ACK, ACK (3-way handshake) works. So NAT shold work in my
environment.
