# Uninstall IPsec/L2TP VPN
|
|
|
|
To remove the VPN:
|
|
|
|
## First step
|
|
```
|
|
service ipsec stop
|
|
service xl2tpd stop
|
|
rm -rf /usr/local/sbin/ipsec /usr/local/libexec/ipsec
|
|
rm -f /etc/init.d/ipsec /lib/systemd/system/ipsec.service
|
|
rm -rf /opt/src/libreswan-*
|
|
```
|
|
|
|
## Second step
|
|
|
|
### For Ubuntu/Debian:
|
|
|
|
`apt-get remove xl2tpd`
|
|
|
|
### For CentOS/RHEL:
|
|
|
|
`yum remove xl2tpd`
|
|
|
|
## Third step
|
|
|
|
### For 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.
|
|
If using IPv6, also edit `/etc/ip6tables.rules` and `/etc/iptables/rules.v6`.
|
|
|
|
### For CentOS/RHEL:
|
|
|
|
Edit `/etc/sysconfig/iptables` and `/etc/sysconfig/ip6tables`
|
|
|
|
## 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`, *except exit 0 (if any)*
|
|
|
|
## Optional
|
|
|
|
Remove these config files:
|
|
* /etc/ipsec.conf
|
|
* /etc/ipsec.secrets
|
|
* /etc/xl2tpd/xl2tpd.conf
|
|
* /etc/ppp/options.xl2tpd
|
|
* /etc/ppp/chap-secrets
|
|
* /etc/ipsec.d/*
|
|
* /etc/pam.d/pluto
|
|
* /etc/sysconfig/pluto
|
|
|
|
copy && paste for fast remove:
|
|
|
|
`sudo rm -f /etc/ipsec.conf /etc/ipsec.secrets /etc/xl2tpd/xl2tpd.conf /etc/ppp/options.xl2tpd /etc/ppp/chap-secrets /etc/ipsec.d/* /etc/pam.d/pluto /etc/sysconfig/pluto`
|
|
|
|
## When finished
|
|
|
|
Reboot your server.
