Thank you for helping

Anything wrong ?

Is there any firewall on the route?

I guess no
Coz my client can connect with OpenVPN GUI (with FreeBSD server)
But it doesn't work with SoftEther

Could you try to use native SoftEther VPN Client?

Okey
I'll try it
But, can you tell me what might be the problem ?
Because my project is to change OpenVPN server to SoftEther server with the same platform for client ( via OpenVPNGUI )

Hey, I have tried it with native SoftEther VPN Client
And it worked :)

But still, I try to change OpenVPN server (FreeBSD) to SoftEther server (CentOS) with the same app for client (via OpenVPNGUI)
Can you tell me what might be the problem, so my client still could use OpenVPN GUI ?

Pleeaassseeee . . . . my boss keep asking me about this

Could you try to update your SoftEther VPN server to latest version.
There is fix about OpenVPN.
