Here are some relevant settings:</p>
<p dir="auto">VPN &gt;&gt; OpenVPN<br />
    Server (tunnel)<br />
        Protocol:      UDP<br />
        Dynamic IP:    yes<br />
        Local port:    1194<br />
        Address pool:  192.168.24.0/23</p>
<p dir="auto">Services &gt;&gt; DHCP Server<br />
    LAN<br />
        Enable DHCP:    yes<br />
        Subnet:        192.168.16.0<br />
        Subnet mask:    255.255.248.0<br />
        Range:          192.168.22.100 to 192.168.23.199<br />
    VPN_open<br />
        Enable DHCP:    ?<br />
        Subnet:        192.168.24.0<br />
        Subnet mask:    255.255.254.0<br />
        Range:          192.168.24.100 to 192.168.25.199</p>
<p dir="auto">If the DHCP Server is not enabled on the VPN interface, connecting clients still seem to get DHCP service and are assigned an address on the 192.168.24.0/23 subnet. If the DHCP Server is enabled on the VPN interface, however, DHCP service on the LAN subnet is interrupted and only static clients and fixed leases seem to get onto the network. The obvious solution is to disable the DHCP Server on the VPN interface, but this seems counterintuitive. Any thoughts?</p>
