Hi @devlin7, and welcome to the community!
You can make these settings permanent by adding them via files in
Create a file
/etc/sysctl.d/10-conntrack.conf with your setting in it:
# fix work PPTP VPN connection issue
net.netfilter.nf_conntrack_helper = 1
and the setting will be applied automatically at boot. The exact filename doesn’t matter, but it is good practice to have it start with a number < 99, because the files are loaded in lexicographical order and there is already
99-sysctl.conf in that folder that is expected to be loaded last.*
As shown above, you can add comments to the file so that you don’t later forget what that setting was supposed to be for.
*there used to be only one config file,
/etc/sysctl.d/99-sysctl.conf is a symlink to that file. That way, if people set something “the old way” in
/etc/sysctl.conf, anything set in there will behave as if it still was the only config file, since it will always be loaded last.
