Eduardo,
parece que houve uma melhora depois que desativei o PF:
--- 10.20.0.2 ping statistics ---
127 packets transmitted, 127 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.163/0.289/0.678/0.067 ms
--- 10.20.0.2 ping statistics ---
109 packets transmitted, 109 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.166/0.313/2.107/0.218 ms
--- 10.20.0.2 ping statistics ---
102 packets transmitted, 102 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.138/0.382/9.108/0.874 ms
