Softether DHCP and NAT

Post by sajer » Tue Aug 26, 2025 7:40 am

Hi!

Common question, i found some answers, yet it doesnt work for me, thus i write this. Thanks in advance!

All i want to achieve is that SoftEther should distribute IP addresses (softether should be the dhcp server) and still access resources on the local network.

Now we use bridged mode and the local dhcp server gives an IP address to the clients, this is what i want to change.

What i did:

Configured Secure NAT and DHCP, deleted the local bridge, created route rule, no success.

So lets say, the local network is 192.168.100.1/24 and i want to access a file server on 192.168.100.200 and i have set up the secure nat to distribute 10.10.10.10-20 IP addresses. It "works", if i connect with the client i get 10.10.10.10 IP address but i cant reach / ping / etc anything on the local network.


What is there correct procedure, to have a local dhcp server and a softether dhcp server too, so the incoming vpn clients get an IP address from softether.

Thanks in advance!

Hi mate! Thanks for the quick response!

The rule was:

10.10.10.0/255.255.255.0/192.168.100.200

Mate, this is no good :)

If the vNIC is 10.10.10.1 then push 192.168.100.200/255.255.255.255/10.10.10.1
