Before posting a question:

If you want to obtain the effective solution for your problem, you should supply the following information when you post the question on this forum. Otherwise, even if a VPN expert cannot answer to your problem.

1. Operating system name and the type of CPU-bits
(e.g. CentOS 6.4 x64)

2. The result of "ifconfig –a" (UNIX) or "ipconfig /all" (Windows)

3. The result of "uname –a" (UNIX) or "systeminfo" (Windows)

4. The build number of SoftEther VPN

5. Which SoftEther VPN component are you using?

6. Whether or not there is a NAT or Firewall between your VPN server and the Internet.
(If there is a NAT or Firewall, you should open a TCP port for the VPN listener.)

7. Are you using SecureNAT?
(If so, why don't you use the Local Bridge function instead?
The performance of SecureNAT is lower than Local Bridge, and it consumes
much of CPU time. You should not use SecureNAT except very limited situation.)
Please see http://www.softether.org/index.php?titl ... T_Function

8. Your current vpn_server.config or vpn_bridge.config file should be attached on the post.
(You may hide your confidential information on these config files if included)

Additionally, your SoftEther VPN issue perhaps came from your misconfiguration or wrong-setting (e.g. making the packet-loop between the Virtual HUB and the physical network adapter) at almost all circumstances, except minority cases. Before posting a question you must carefully check your configuration.

Good luck!
