IP not assigned to Softether VPN clients

Post by azizbekoff » Thu Jul 08, 2021 6:35 am

Hi,

I have installed SoftEtherVPN Server on Windows Server 2012 R2(on Vmware Esxi Host). Client is installed on Windows 7.

VPN Client can connect. but IP not assigned by DHCP
configured with local bridge. SecureNAT disabled.
Added second NIC with no IP

Additional details:
Local bridge is added, pointed to second NIC with no IP(VMXNET3)
1st Virtual network adapter:Intel type:e100e
Promiscuous mode: Allowed

Any suggestions are appreciated!

With best regards,
azizbekoff

In the network the second NIC connects to, is there a DHCP server? I should ask this way.
Also, is the second NIC in promisc mode too?

2. Yes, promisc mode enabled on vlan level

I don’t understand. What do you mean by promisc mode at vlan level? If the nic is virtualized, promisc mode needs to be applied from the top level.

For a test please remove local bridge and enable SecureNAT (with all defaults).

If it works now, describe your server's environment and setup.

Yes you can "separate" it. Again, remove local bridge (the one within SE) and enable SecureNAT, and SE clients will get proper DHCP assignments.

Next, enable Virtual NAT, and SE clients will get connectivity.

Hello, I wrote "remove local bridge (the one within SE) and enable SecureNAT", and it will work for sure.
Incidentally, if you enable "MAC Address Spoofing" in advanced settings of the virtual NIC, your current config may work too.

Yes SecureNAT is great. If you insist on a bridged connection then a vNIC with "MAC Address Spoofing" and NIC in promiscuous mode are required. That's why.

Either bridge to the LAN adapter or try a better WiFi adapter.
