SoftEther VPN User Forum

My conclusion is that bridging the VPN hub to a tap device simply does not work, maybe this is why there is such little information available on this topic.

It seems that SoftEther is designed mainly for NAT and though the performance is lower, I will stick with NAT.

Briding to tap works great, but If you don't like NAT, you have to set routing rules on BOTH sides of the network. And the performance loss should not be huge, if doing NAT by iptables.

Please explain more detail about your problem.
How do you know the tap device is not working?
