Generating wrong subnet when running add peer and configuration scripts

Closed this issue · 2 comments

When creating new configurations, it asks me for the machine's internal IP, which I assume is going to be from here:

but it keeps giving me error, a quick inspection shows that 10.0.0.64 is being converted to 10.0.0.64/24 and written to settings/ipv4

image

subsequently, the helper script will append 0/24 to the IP

image

it results in something weird like 10.0.0.64/240/24, which is not a valid CIDR.

Is there a bug within the script? or am I understanding something wrong?

  • When it asked for port, I entered 51820
  • When it asked for IP, I entered 10.0.0.64
  • wg then gives me error in various places complaining 10.0.0.64/240/32 cannot be parsed.

Hello @junzhengca ,
The script asks you to vpn's internal server ip. This is not related with your server ip adress. The script ask which ip adress should assign for clients. For my personal server, I typed 10.66.66.1 and when I create one more peer, internal vpn adress should be 10.66.66.2. This means wg will identify this client with 10.66.66.2. If you enter you server's ip, it will cause IP conflict.
