Allow non-SoftEther VPN Software to connect

Post by smartgig » Tue Apr 28, 2015 4:29 pm

Hello,

I want to connect to my SoftEther VPN Server using Cisco AnyConnect on my android device.

Currently I get the following error when I try to connect:
"A client which is non-SoftEther VPN software has connected to the port 443"

Is it possible to disable this limitation on SoftEther Server?

I think Cisco AnyConnect doesn't support any protocol SoftEther provides.

If the connection remains stable, this is not an error.
On Android I use OpenVPN for connection.

Works like a charm.

no the connection couldn't be established at all and softether rejects the connection with the above error.

OpenVPN is great but it doesn't work if you're behind a firewall.

You can setup your openvpn to use TCP on port 443 instead of UDP:1xxxx ( I don't remember the default port for openvpn). This should allow you to bypass a firewall at the cost of lower bandwidth.

OR

Android has a built in VPN client that uses L2TP/IPsec protocol which works fine with Softether. But if you are behind a very restrictive firewall, it might not work.

But I guess this wouldn't work on a firewall with packet filtering which only allows HTTP and HTTPS data to be transferred through ports 80 and 443, would it?

The first method should work as there is no way for the firewall to know what is inside the packet (because it is encrypted for both https and openvpn).

Did you solve this?
I have a device that supports openVPN but getting the same error
