Cannot establish multiple connections to SoftEther

Post by vimal7370 » Tue May 23, 2017 12:05 pm

Hi all,

I have successfully installed SoftEther VPN Server and created users in it. The issue I have is that I am unable to establish more than 1 connection to SoftEther VPN from my local network. My Android mobile is connected to wifi and because it is the first device from this public IP, it connects fine. Now, if I try to establish connection from my Macbook which is connected to the same wifi network (i.e., on the same public IP), it fails. The logs says:

2017-05-23 15:20:03.020 IPsec Client 79 (14.231.195.110:32717 -> 50.74.7.145:500): A new IPsec client is created.

Also, there seem to be a limit regarding TCP connections (set to value 1) which I seem to hit [screenshot attached] and I do not seem to locate the place where I can modify/increase this value.

NOTE: I can use the same user/pass credentials to connect simultaneously from two or more devices as long as they are on different public IPs. The issue is only when I connect from same network.

Please assist.

If VPN passthrough function available in your network router, please enable it.
or
Please try OpenVPN.
