PF and states of connections with same src port

[B A]

Hello!



I have question about PF.



I have just found interesting behavior of of PF.

For example if I fix source port and run from my PC:

   echo 'aaaaaaa' | nc -p 3333 www.my.rerver 80

I got response.

But if I just run this command again - connection stuck.

I should wait about 1 min to be able make connection with

same src port. Looks like ps states didn'd imediately removed after

FIN send.

Directly connected PC haven't show such behavior, I got response immediately.



Am I wrong or something about PF? How can fix this behavior? 



Thank you.
