I just created a review with the following description: Allow TCP to reuse local port with different destinations Summary: Previously, tcp_connect() would bind a local port before connecting, forcing the local port to be unique across all outgoing TCP connections for the address family. Instead, choose a local port after selecting the destination and the local address, requiring only that the tuple is unique. The review is https://reviews.freebsd.org/D24781. The change originated on the Sidewinder firewall, which is proxy-based as well as packet-filter based, and needed to support more proxy connections than the pool of ephemeral ports as long as the destinations were different.
