Saya memiliki kotak Debian Jessie di 192.168.1.5 yang terhubung ke router (pada 192.168.1.1) yang menjalankan klien OpenVPN (sebenarnya Pi menggunakan pengaturan ini . Satu-satunya bagian yang berbeda adalah bahwa IP eth0 Pi statis karena router, yaitu, Pi menggunakan DHCP router).
Ketika klien LAN diatur untuk menggunakan 192.168.1.5 sebagai gateway mereka, mereka berada di VPN, sebagaimana dimaksud.
Yang saya butuhkan adalah untuk memiliki klien LAN dalam 192.168.1.128/25 memiliki semua lalu lintas mereka dialihkan ke 192.168.1.5, bahkan ketika IP mereka diatur oleh DHCP router dan gateway mereka menjadi 192.168.1.1. Dengan kata lain, klien dalam 192.168.1.128/25 harus berfungsi seolah-olah gateway mereka adalah 192.168.1.5.
Apa iptables
dan / atau route add
pengaturan yang harus dilakukan router untuk melakukan ini (router menjalankan Tomat 3.4-138)? Ini adalah pengaturan router:
