First problem: FreeBSD appears to be re-using source ports too
rapidly. My understanding is that a TCP socket ({src IP, src port,
dst IP, dst port} tuple) should not be re-used for 120 seconds after
teardown. Sample tcpdumps and IPfilter whinges below show reuse
after 66 and 83 seconds.
That's an incorrect understanding. TIME_WAIT recycling has been in the
BSD network stack for a long time, and Windows/Linux handle it also.
IPFilter is clearly broken if it's blocking the reuse of the port after 66
seconds. You should ask Darren to fix its state table.
