PFsense too slow NAT connection problem Fixed !


– Ping works with no problem,  from LAN to LAN,
from WAN to WAN and any cross-subnet combination with the correct NAT/gateway rules.
– TCP connections work in one way or between specific hosts, but in one direction to WAN or from WAN they don’t work,

Slow traffic (~5.67 Kbps)  !!!!
– UDP  work sometimes,


First :  Login  Host machine,   SERVER which is Main

Second: Open pfsense
Disable the hardware checksum offload.
