11.1.2 I am unable to communicate with the IP address of the Virtual Network Adapter used for local bridging from within the VPN.

If you are using Linux or Solaris, you can communicate within the Virtual Hub (VPN) from the network adapter connected to by the local bridge to the LAN, but you can not communicate to the network adapter itself. This is a restriction imposed by the Linux kernel. For more information please refer to 3.6 Local Bridges.
If you are using local bridging to make a bridged connection between a Virtual Hub and a physical LAN as described in section 3.6 Local Bridges, we recommend you set aside a network adapter specifically for this purpose. This will result in the best performance when using local bridging.

I Have Enabled Local Bridge Also but still not able to Ping Local Server

It has to be a double bridge with SE soft tap.

Code: Select all

  vHUB+++TAP+++
              +
             br0
              +
         NIC+++
