Subject: Beyond 64K TCP connections limit per IP-address

If I am correct, a TCP server can make up to
64K accepts for a port at a single IP-address.

If one would like to have e.g. 1M TCP connections
to a single IP-address of a powerful server (without load balancer),
how to make such setup?

There is a workaround to arrange several secondary IP-addresses
each serving ~64K connections.
Any other options?

Server places to the outgoing packet source port the port
of the server listening socket. Actually, the ephemeral ports at the
server side are used as the hashing keys.
Could it be played, tricked somehow?

Y comments would be appreciated.
