Softether and MacOSX - DHCP issues

Hey,

I tried to setup Softether on a Windows 10 Computer as Server using L2TP VPN over IPSEC, which overall seems to work, but not completely as intended
- Using another Windows Computer along with the SoftEther Client I can successfully connect to the VPN Server
- Using a MacOSX Laptop I can connect to the Server at the first attemp. If I disconnect once from the Network I can't reconnect again. (After I restart the VPN Server i can then reconnect again)

I enabled the SecureNAT function, which might be part of the issue.

When I connect to the VPN Server via the local IP while being in the same Network my macOSX pulls an IP from Softether (192.168.30.10 for example)
At the same time the WIFI Module of the MacOSX gets another IP address of the SecureNAT Application (192.168.30.31)

Again, after a reboot of the Server I can reconnect to the VPN Server again. Should I turn off DHCP and enable static IP to avoid the IP issues?

Also: When I connect via the Windows Client it only works when NAT-Traversal is enabled. As soon as I disable NAT Traversal I'm no longer able to connect to the VPN, even though this is a home network, so there is no firewalls in between or something

Thank you very much for your help
