Description:
If I try to create the left subnet of 10.250.0.0/16 the libreswan config ends up with a leftsubnets value of 0.0.0.0/0
I believe that this is bacause the /etc/init.d/ipsec uses ` [[ "$leftsubnets" =~ 0.0.0.0* ]] && leftsubnets="0.0.0.0/0"`
I think this should be `=~ 0\.0\.0\.0.*` but my shell knowledge is not great enough to be sure.

Research direction
Start in /etc/init.d/ipsec, focusing on the leftsubnets pattern mentioned in the issue and how the libreswan configuration is built. Reproduce the configuration with a left subnet of 10.250.0.0/16, then verify that it remains that subnet instead of being changed to 0.0.0.0/0.
