I've the TIME WAIT parameter like:

# TIME_WAIT seconds
net.ipv4.tcp_fin_timeout = 30

# Recycle and Reuse TIME_WAIT sockets faster
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1

so the machine should liberate the port after 60 seconds I think... but it's not working, still at TIME WAIT for 60 seconds more...

I think that the problem can be the firewall, but I need confirm that

Anyone Can help me?
