Automatic add routes when PPTP client connects to PPTP server

Lama blm sempet update dan bikin catatan yang maksud dan tujuan nya adalah menambahkan static route di PPTP server ketika PPTP clinet konek karena ini di pake untuk site to site, berjalan baik di centos dan debian

Site 1 (pptp server) debian 9
ip pub = 103.xx.xx.xx
ip pptp server = 10.101.1.1
Lan site 1 = 10.10.0.0/24

Site 2 (pptp client) mikrotik
ip pub = 103.xx.xx.xx
ip pptp client = 10.101.1.10
Lan site 2 = - 192.168.0.0/24
                      -  192.168.2.0/24
                      -  192.168.25.0/24


Site 3 (pptp client) mikrotik
ip pub = 103.xx.xx.xx
ip pptp client = 10.101.1.15
Lan site 3 =  192.168.10.0/24

Kurang lebih topologi nya sbb

Langsung saja bikin file di /etc/ppp/ip-up.local yang isi nya sbb

#!/bin/bash
case "$5" in
    10.101.1.10)
        /sbin/route add -net 192.168.0.0/24 gw 10.101.1.10
        /sbin/route add -net 192.168.2.0/24 gw 10.101.1.10
        /sbin/route add -net 192.168.25.0/24 gw 10.101.1.10
        ;;
esac


dimana $5 adalah ip tujan remote untuk debian bisa baca di /etc/ppp/ip-up
berikut cuplikan nya file /etc/ppp/ip-up
# This script is called with the following arguments:
#    Arg  Name                          Example
#    $1   Interface name                ppp0
#    $2   The tty                       ttyS1
#    $3   The link speed                38400
#    $4   Local IP number               12.34.56.78
#    $5   Peer  IP number               12.34.56.99
#    $6   Optional ``ipparam'' value    foo


root@debian:/home# /etc/init.d/pptpd restart
connect dan di connect pptp clinet cek hasil route nya
root@debian:/home# route -n


untuk multi multi client misal site 1  site 2 dan site 3 sbb

#!/bin/bash

case "$5" in
    10.101.1.10)
                /sbin/route add -net 192.168.0.0/24 gw 10.101.1.10
                /sbin/route add -net 192.168.2.0/24 gw 10.101.1.10
                /sbin/route add -net 192.168.25.0/24 gw 10.101.1.10
                ;;
    10.101.1.15)
                /sbin/route add -net 192.168.10.0/24 gw 10.101.1.10
                ;;
        *)
esac
