Packet Loss from VPN clients
Posted: Thu Sep 03, 2020 11:32 pm
Hello,
I have installed SoftEther VPN Server in a small business environment. The setup is as follows.
There is a Cloud IP address which remote users connect to. TCP 5555 and UDP 500 and 4500 and forwarded from there, through the WAN IP's to the LAN IP of the SoftEther VPN Server. The Server is using SecureNAT to enable split tunneling. The load is very small on the server as there is only about 40 users max. The VPN clients outside are able to connect, but drop packets to the DNS server inside the network on the other side of the SoftEtherVPN server. The server inside the network does not, and other servers and workstations inside the network do not. The packet loss to the VPN clients is around 70%. I have tried tracing and checking the logs and all I find is that many requests are being made, and many are not being answered. More info, the SoftEtherVPN server is running windows 2016 and it is a guest on a 2016 Hyper-v host server. The DNS server is on a different Hyper-V 2016 host server and is a 2012R2 guest.
This issue is driving me nuts and it may not even be SoftEther VPN's fault. Does anyone have any ideas to assist in narrowing down this issue please?
Thanks,
Mike
