SoftEther VPN User Forum

Hi guys !
I am facing failure to connect on any port of the SoftEther server thought all virtual adpaters on client side are connected.
The ports are open on the Windows firewall and SoftEher Server is autorized.
The final target is to connect to Firebird Server (port = 3050) from remote client application.
Below are my configurations and tests. Any help will be really appreciate.
Regards.

Server (PC0, 192.168.1.4 on wifi)
System : Windows 2010.

Configuration server side
Protocol : TCP/IP;
Local bridge : disabled;
VPN Azure : disabled;
SecureNat : enabled;
Virtual host IP = 192.168.30.1;
DHCP (192.168.30.10, 192.168.30.11, 192.168.30.12 & 192.168.30.13).

Tests server side
netstat -an | findstr 443 => LISTENING;
netstat -an | findstr 992 => LISTENING;
netstat -an | findstr 5555 => LISTENING;
netstat -an | findstr 8888 => LISTENING.

Client (PC1, 192.168.1.8 on wifi)
System : Windows 2010.

Configuration client side
4 Virtual network adapter;
4 VPN connection,
192.168.30.10, port = 443;
192.168.30.11, port = 992;
192.168.30.12, port = 5555;
192.168.30.13, port = 8888.

Tests client side
ping 192.168.30.1 => Okay : 100% / 4ms;
ping 192.168.30.10 => Okay : 100% / 0ms;
ping 192.168.30.11 => Okay : 100% / 0ms;
ping 192.168.30.12 => Okay : 100% / 0ms;
ping 192.168.30.13 => Okay : 100% / 0ms.

telnet 192.168.30.1 443 => Could not open connection to the host, on port 443: Connect failed;
telnet 192.168.30.10 443 => Could not open connection to the host, on port 443: Connect failed;
telnet 192.168.30.10 992 => Could not open connection to the host, on port 992: Connect failed;
telnet 192.168.30.10 5555 => Could not open connection to the host, on port 5555: Connect failed;
telnet 192.168.30.10 8888 => Could not open connection to the host, on port 8888: Connect failed.

Telnet to the host's LAN IP, not to 192.168.30.1 - more info Client PC unable to reach shared directory on Server PC

If server and client LANs are on the same subnet, in SecureNAT's "Edit the static routing table to push" add eg: 192.168.0.2/255.255.255.255/192.168.30.1

You can't test both VPN server and client on the same LAN. Connect the client from a different PC via eg mobile hotspot.

Thank you so much Solo.
The client is under 4G and Telnet to 41.208.133.1 443 works fine, 41.208.133.1 being the LAN IP.
This said, I am confused not using Telnet with 192.168.30.1 (and 192.168.30.10 to 13?). First, because the LAN IP use to change, second, I am wondering how can I reach the port 3050 under SoftEther as this is the final goal ?
In advance thank for helping.
Regards.

41.208.133.1 is a WAN IP, it can't be used for LANs.

Firebird Server (port = 3050) = VNC = RDP = FTP = SMB = etc. = Client PC unable to reach shared directory on Server PC
