Access VPN Bridge services

Post by ltilley » Tue Jan 09, 2018 8:04 pm

Hi,

I have a network topology that looks like this:

Remote Clients ----> Soft Ether VPN Server on VPS <------- VPN Bridge on my Local LAN ----> Local LAN

the VPN Bridge has a cascade connection set up to the VPN Server on my VPS and I'm wondering how I can set it up so that the server that the VPN Bridge is running on is accessible. Currently, whenever I try to ssh into the server with the VPN bridge on it, it won't respond to the connection. However, when I ssh into another server on my local LAN, then open a second ssh connection from there, it works fine.

What OS are you using?

Except Windows, localbridge not in tap mode can't communicate the host OS itself.

Yes.
The host OS of VPN Server/Bridge can't receive packet from a localbridge(not tap).
But the localbridge can send packets to the LAN.
And also the eth device can communicate with the LAN normally.
Only communication between virtual hub and the host OS will fail.

To avoid this, it is common to use the tap mode localbridge and linux bridge.
There are many topics on actual usage.
