SoftEther VPN User Forum

I upgraded Server from version 9505 to version 9529.
All OpenVPN clients have problem to connect. All my clients is running under OpenWRT linux.

/log:
Channel 0: Acquiring an IP address from the DHCP server failed. To accept a PPP session, you need to have a DHCP server. Make sure that a DHCP server is working normally in the Ethernet segment which the Virtual Hub belongs to. If you do not have a DHCP server, you can use the Virtual DHCP function of the SecureNAT on the Virtual Hub instead.
Channel 0: Failed to connect a channel.
/endlog
