Hi there.
It has been confirmed that the network speed of the server with Sangfor HCI installed is decreasing. Can I know the cause and how to resolve it?
Currently, there are IP: 192.1.1.141(A) and 192.1.1.142(B) servers connected to one switch hub, but there is nothing wrong with B server, but only A server is the problem

Hi, it appears that the network card's speed has dropped due to a failed negotiation for gigabit speed. Consider manually setting a fixed speed on the network card or on the switch itself to ensure the NIC consistently operates at 1000 Mbps full-duplex.
Is this answer helpful?

Hello Dear
tunnel nat refers to the ability to remap a network to a different class IP on an IPSec SDW tunnel. It is helpful in situations where the same network segment is present on both sides of the ipsec sdwan. To make sure that the traffic is routed appropriately on both sides, keep in mind that you must create this NAT on both ipsec sides and use two false class IPs.
