Open VPn will not start with /16 subnet
Hello, I am by no means a routing expert in any sense of the word. I have been trying to setup openVPN and it will not start if I set it up with the subnet our office uses. Our network is 192.168.xxx.xxx/16 if I configure Open VPN it to use /16 it will not start. What should I be using as an IP range in Open VPN. What other information do you need to help me resolve this. I had set it up as a test with a 192.168.1.XXX/24 and it started and I could connect to the router via open VPN but the inside network was not accessible nor could they go outside to the internet.
Well since your using ALL the 192.168 space.. your tunnel would have to be using something out of the 172.16/12 space or the 10/8 space..
Why would you be using such a large network? Do you have some 65K clients on this network?
Set your local network to be something realistic.. How many clients do you have? And then use a tunnel network that is not inside that space.
Say for example 192.168.0/24 or 192.168.0/23 if you had say some 500 devices on your network. Then use something other for your tunnel, say 192.168.2/24
