Hello,
We have problem with data transfer performance via VPN in our lab environment.
Topology:
Cluster of 2 VM Gateways
Windows VPN client
MacOS ssh server
When we are transferring data over LAN (between two networks) speed of 3GB file transfer is some about 200Mbps
When we are transferring data over VPN speed of 3GB file transfer is some about 20Mbps (WinSCP)
Lab environment hasn't any performance problems (CPU of active gateway is about 5%)
WAN network is 1Gbps/1Gbps on every site.
ESP: AES-256 + SHA256 (we tried lower security algorithms, but nothing changes)
Scheme: IKE
How can we increase VPN network performance
