Read this in other languages: English, 简体中文.
Follow these steps to remove the VPN. Commands must be run as root, or with sudo.
Steps
First step
service ipsec stop
service xl2tpd stop
rm -rf /usr/local/sbin/ipsec /usr/local/libexec/ipsec
rm -f /etc/init/ipsec.conf /lib/systemd/system/ipsec.service \
/etc/init.d/ipsec /usr/lib/systemd/system/ipsec.service
Second step
Ubuntu/Debian
apt-get purge xl2tpd
CentOS/RHEL
yum remove xl2tpd
Third step
Ubuntu/Debian
Edit /etc/iptables.rules and remove unneeded rules. Your original rules (if any) are backed up as /etc/iptables.rules.old-date-time. In addition, edit /etc/iptables/rules.v4 if the file exists.
CentOS/RHEL
Edit /etc/sysconfig/iptables and remove unneeded rules. Your original rules (if any) are backed up as /etc/sysconfig/iptables.old-date-time.
Note: If using CentOS/RHEL 8 and firewalld was active during VPN setup, nftables may be configured. Edit /etc/sysconfig/nftables.conf and remove unneeded rules. Your original rules are backed up as /etc/sysconfig/nftables.conf.old-date-time.
Fourth step
Edit /etc/sysctl.conf and remove the lines after # Added by hwdsl2 VPN script.
Edit /etc/rc.local and remove the lines after # Added by hwdsl2 VPN script. DO NOT remove exit 0 (if any).
