SoftEther VPN User Forum

Hi,

I need to create a LAN-2-LAN between 2 sites, as specified in :
https://www.softether.org/4-docs/1-manu ... L2_Bridge)

I created on one site, on a W2016 server, the main SE VPN Server,

I created on second site, on a W2016 server, a SE VPN Bridge.
This server is a VM under ESXi 6.7, and has 2 NIC (identical : VMXNET3).

When trying to create the Local Bridge, it displays only the first NIC. Not the second one.
But for me, they are identical.

I need a second NIC, because relying on the first NIC (which has in this case 2 local networks) create CPU hungs, and huge latencies (loops ?).

Of course, I deleted/recreated second NIC, rebooted several times, ...
Also changed "ShowAllinterfaces" to true, in SE Settings :
But in all cases, second NIC is not visible.

So, no more ideas for me. If someone has a good idea ?

Sylvain

Please post as code from the SE Bridge VM:

Hi,

Thanks a lot for your reply.

Get-Adapter returns my 2 NICs, same driver, different names, one with promiscuousmode TRUE, the other FALSE.

BridgeDeviceList returns also the 2 NIC.

BridgeList returns ONE association VPN<->NIC, with VPN Name="BRIDGE" (which is NOT the name of my vHUB, which is "VPN"), and with the NIC, not visible in the admin GUI.

Is "BridgeList" supposed to list the "local VPN Bridges" ?

So, I decided to re-read the documentation to well understand the concepts. Is there any tuto or doc more detailed on installing a LAN2LAN sith SE ?

Get-Adapter returns... one with promiscuousmode TRUE, the other FALSE.

That's it. To get the 'FALSE' NIC visible on "local bridge" settings, in ESXi set:

• promiscuous mode enabled
• mac address changes enabled
• forged transmits enabled

Yes, thanks a lot for these informations.
I have already set promiscuousmode=Enabled, on ESXi, but not the 2 others settings.

Unfortunately, even after reboot of the VM, nothing changed.
Strange thing : both NIC card are same type (VMXNET3), and one is promiscuous=ON, the other OFF.

Enable the 2 other settings and on the host run "esxcli network firewall set -enabled false", reboot. If still no go...

Please post as code from the SE Bridge VM:

Code: Select all

ipconfig /all
PS> Get-NetAdapter | Format-List -Property ifAlias,InterfaceDescription,PromiscuousMode
vpncmd localhost:port /server /password:*** /cmd BridgeDeviceList
vpncmd localhost:port /server /password:*** /cmd BridgeList
//replace: *** with SE admin password

VERBATIM data output, not your commentary about it. In addition, from the VM host: Redact public IP and private info, if any, but do not remove anything.
