Connection between two IPsec vpnserver!THANK YOU!

Post by zedyasuo » Mon May 11, 2020 7:59 am

Hi everyone,

I want to make an IPsec establishment between two vpnservers(rather than vpnclient-vpnserver normally),

I enabled "L2TP over IPsec Server Function" by using vpncmd->IPsecEnable in both SoftEther VPNs

But I don't know how to let either start a IPsec connection targeted the other one,

Or maybe the vpnserver doesn't support this,

Anyone Know this?

I will thank you very much!!!!!

Yours

A "SE-Server" or "SE-Bridge" can only make outbound connections using the "Cassade Connection" option which uses the SE- Ethernet over SSL protocol. The casscade connection is designed to connect SE- Servers or SE- Bridges and SE- Servers to each other.

However the SE-Server can "receive" connections from various protocols. SE-over SSL, OpenVPN, MS-SSTP, L2Tp/IPsec.

Hi, man,
I want to use vpncmd to config "cascade connection" between SE- Servers and SE- Bridges, as I don't have a Windows GUI environment
I saw some commands start with "Cascade" such as "CascadeCreate","CascadeList","CascadeGet","CascadeSet" and so on in vpncmd.
I have tried some commands above, but sadly, I failed to create a "cascade connection".

I read some documents about vpncmd in https://www.softether.org/
But I don't know the exact steps to create a "cascade connection" within vpncmd

Could you tell me how to do that? Or give me the weblink of documents about "create a cascade connection within vpncmd".

Thank you very much!!!

Regards.

Hey man, Here I come again, lol.
I have set up a layer-2 "Cascade Connection" like the attachment:

My question is : How can I start a "IPsec Connection" through the "Cascade Connection"?

I have tried the followings: Before I start the "Cascade Connection", I set "IPsecEnable->L2TP over IPsec" the value of "yes".
Then I start "Cascade Connection".
However, it seems the established "Cascade Connection" is still a normal "Cascade Connection". It wasn't a "L2Tp/IPsec" connection.

Anyone Know this?

I will thank you very much!!!!!

Yours

The L2TP/IPsec feature on SE-server is only for RECEIVING connection from L2TP/IPsec supported clients/devices. (Windows , Iphone. Android, MAC or 3rd party clients.) I believe ""IPsecEnable->L2TP over IPsec" the value of "yes"." activates this feature so the SE-Server can function as a L2tp/Ipsec SERVER (Receive connections). The "SE-Server", "SE-Bridge" or "SE-client" software ONLY uses the SE- Ethernet over SSL protocol to make OUTBOUND connections. They DO NOT use the L2TP/IPsec protocols to make OUTBOUND connections. If you insist on using the L2TP/IPsec protocols to connect the 2 locations you will need to find some other software to make the connection to the SE-Server. However, the cascaded connection you created is already an Secure/Encrypted connection. I'm not sure why the other protocol is required.
