Firewall Config
Not very complete, firewalld commands untested
Server configuration
I used the server setup on CentOS 7 and want to give some feedback.
Overall the setup has been good, but the second firewall-cmd didn't work on my system. Instead I used the following command for enabling the masquerade.
firewall-cmd --add-masquerade
Further I am curios about two things regarding the setup. First of all, why the ln -s ... command? A systemctl enable … looks to me sufficient. The other thing I am curious are the sample server setups. Why is the roadwarrior-server.conf used or why is it preverable over the server.conf?
