Access to other virtual machine (run with Switch Embedded Teaming) is very slow

Post by QianMX » Wed Dec 29, 2021 7:45 am

I have these servers:
1. physics machine P1:
- virtual machine V1
- virtual machine VPN (SecureNAT and MAC address spoofing is enable)
2. physics machine P2:
- virtual machine V2

Expected behavior:
I can normally access all servers through VPN

Actual behavior:
I can normally access all servers in local network.
I can normally access all servers in VPN server.
I can normally access P1,V1 servers with softether.
But,Both P2 and V2 servers are very slow when accessing websites or RDP with softether

Steps to reproduce:
1. Enable Switch Embedded Teaming in P1、P2

Code: Select all

New-VMSwitch -Name "SET Team" -NetAdapterName "NIC1","NIC2"
Set-VMSwitchTeam -Name "SET Team" -LoadBalancingAlgorithm Dynamic
2. Assign `SET Team` switch to virtual machines, enable MAC address spoofing in VPN server.
3. Install softether and enable SecureNAT
5. Open port 5555 to the Internet in the router
6. I use RDP to access P2 and V2 servers very slowly,click the button and wait 10 seconds to respond
7. If I change `DisableKernelModeSecureNAT` to `true`, i can normally access P2 and V2 servers.
However, the SQL connection cannot keep alive and will be disconnected in about 20 seconds

If I need to use Switch Embedded Teaming, how can I solve this problem?
