Bir OpenVPN istemcisini çalıştıran yönlendiriciye (192.168.1.1'de) bağlı 192.168.1.5'te bir Debian Jessie kutusu var (aslında bu kurulumu kullanan bir Pi'dir . yani, Pi yönlendiricinin DHCP'sini kullanıyor).
LAN istemcileri, ağ geçidi olarak 192.168.1.5 kullanacak şekilde ayarlandığında, istenildiği gibi VPN'dedirler.
İhtiyacım olan, 192.168.1.128/25 dahilindeki LAN istemcilerinin IP'leri yönlendiricinin DHCP'si tarafından ayarlandığında ve ağ geçidi 192.168.1.1 olduğunda bile tüm trafiklerinin 192.168.1.5'e yönlendirilmesini sağlamak . Başka bir deyişle, 192.168.1.128/25 içindeki müşteriler, ağ geçitleri 192.168.1.5 idi.
Yönlendiricinin bunu yapmak için yapması gereken iptables
ve / veya route add
kurulumu nedir (yönlendirici Domates 3.4-138 kullanıyor)? Bunlar yönlendirici ayarları:
