Yes. I even tried to bind it to different IP addresses on the local
machine (using alias), but still he max connections with ephemeral
ports wont go over the port_range value.

But, if I specify a port while binding with different IP address, then
I am able to reuse the port.
So it seems like the ephemeral port selection part in the kernel only
provides a max of

net.ipv4.ip_local_port_range = 3000     64000

values.
