|
|
* [Second step](#second-step)
|
|
* [Third step](#third-step)
|
|
* [Fourth step](#fourth-step)
|

|
|
* [When finished](#when-finished)
|
|
|
|
## First step
|
|
|
|
```bash
|
|
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 & Amazon Linux 2
|
|
|
|
`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 & Amazon Linux 2
|
|
|
|
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).
|
|
|
|
## Optional
|
|
|
|
**Note:** This step is optional.
|
|
|
|
Remove these config files:
|
|
|
|
* /etc/ipsec.conf*
|
|
* /etc/ipsec.secrets*
|
|
* /etc/ppp/chap-secrets*
|
|
* /etc/ppp/options.xl2tpd*
|
|
* /etc/pam.d/pluto
|
|
* /etc/sysconfig/pluto
|
|
* /etc/default/pluto
|
|
* /etc/ipsec.d (directory)
|
|
* /etc/xl2tpd (directory)
|
|
|
|
Copy and paste for fast removal:
|
|
|
|
```bash
|
|
rm -f /etc/ipsec.conf* /etc/ipsec.secrets* /etc/ppp/chap-secrets* /etc/ppp/options.xl2tpd* \
|
|
/etc/pam.d/pluto /etc/sysconfig/pluto /etc/default/pluto
|
|
rm -rf /etc/ipsec.d /etc/xl2tpd
|
|
```
|
|
|
|
## When finished
|
|
|
|
Reboot your server.
