Problem with connection after assigning a client fixed ip

ekachaiz

Hi guy, I have been trying to figure this out for 2 days now but still cant get it to work. Im currently using My Asus router as Openvpn server with configuration below. There are 3 clients connect to the server. Everything works fine under this setting until i try to assign a static ip to one of the client. I have added a file "user01" to ccd folder. The "user01" ip address shown according to my setting but internet connection and connection between other clients become impossible. Im not sure what I've done wrong here. It would be much appreciated if anyone could point out my mistake here. I've read the topology subnet topic but still not quite sure if im understand correctly.

i think this should be reversed

ifconfig-push 10.8.0.1 10.8.0.2

but you should not use the first /30 subnet for fixed IP in topology net30
try

ifconfig-push 10.8.0.10 10.8.0.9

this is from the clients prespective so the first IP is the local enpoint (Client IP) , second is the server's IP

also , it's recommended to use 'topology subnet' instead of the default 'topology net30'
