Thanks for the reply. I have commented 3 lines as described but after that also did not get connected to the server. OpenVPN GUI logs do not show any errors but not getting connected with the server too.
NOTE: I'm trying to connect to OpenVPN GUI tool from my laptop & in my laptop I'm using my own mobile internet through wifi. I can access the router's WAN public IP and open WebUI of it. But not getting connected to OpenVPN Server.
NOTE: When M used RUT955 wireless connection (wifi) to my PC, It got connected. But If I Switch to my own wifi network to PC then It's not get connected. To allow any other network do I need to add some settings in RUT955?
