SoftEther VPN hub DHCP problem

Post by akbarsdigital » Thu Oct 03, 2019 9:19 am

Hi everyone!
When user connects to the HUB he is resieve the link local DHCP address 169.254.x.x, but the server give the right IP address. But on other hubs everything works correctly, what could be the problem? I attach ipconfig files and a log with wireshark.
