Hey dude, not much clear about your topology.

Maybe you can capture some screenshots of your setting in the Router and client, so that I can help to have a check.

Hi Dude, it seems can't support more than 256 IP address. You can change the LAN IP subnet first then when you try to change DHCP Server setting to make it can allocate, it will say the ip address...

As I know, the ER6120 V1 can only support one account to set as 0.0.0.0. It was improved in V2.

If the port 1723 closed sometimes, maybe there is something in your network attack to make the router close it. So it stop working. I am not sure what it is. Maybe you can find some in the log?
