SoftEther VPN User Forum

Hello,
Yesterday i installed Softether VPN server on a Microsoft Windows 2003 Enterprise Server, and Clients on 4 machines, 2 being XP, 1 Win7 and 1 Win8.1
It all worked like a charm, untill it stopped, and now no1 can connect.
I tried pinging Dyndns addres and its reachable, the Virtual Hub on server is Online.

Does any1 knw why it would suddenly stop working?

Post your server log, especially the part when the clients try to connect.

Maybe a firewall configuration was not made permanent and a firewall restart has reset any port forwarding you had configured during VPN Server install. Please note that I'm just guessing here being that you don't mention how the VPN Server is being accessed from the internet! For instance, how is it that you are able to see that the Virtual Hub is online? Are you on the same LAN as the VPN Server?

The more details you can provide for us to get a glimpse of your topology, the faster we can provide a solution.

ak.

Im adding the last 3 logfiles.

There is no firewall either on server or the router.

Im on the sam LAN as the server, but the clients are on remote locations.

The server is behind NAT and dynamic public IP.

On Friday night i restarted the server and VPN worked again, today i checked and it stopped working again, after another reset it works, but im guessing tomorrow it will stop again. My best guess is that it stops when ISP adress changes, but i can ping dyndns address even when the VPN is down, so im a bit confused here.

The only suspicious things i see in these logs is this:

For some reason it seems local bridge disconnected...it wasnt by my doing.

And also:

2015-12-04 13:20:35.745 Session "SID-xxxx-104": The parameter has been set. Max number of TCP connections: 2

Why is it showing max number of TCP connections as 2, i havent set that up, is it a default value?

Today not even the restarts are helping, does anyone have an idea what could be wrong, or its just broken software?

Did you configure port forwarding on router?
When the client has been disconnected in the server log?
A server which is not yours will answer a ping.
