Tambahan di konfigurasi /etc/openvpn/server.conf
ifconfig 10.8.0.1 255.255.255.0 server 10.8.0.0 255.255.255.0 # tun-ipv6 server-ipv6 2345::/64 route-ipv6 2003::/64 2345::2 # routing ke arah LAN client client-config-dir client
Tambahan di /etc/openvpn/client
File: client # tergantung username client.ovpn ifconfig-push 10.8.0.2 255.255.255.0 # paksa IP static di client untuk memudahkan routing push "route 10.10.10.0 255.255.255.0" # paksa routing ke upstream iroute 10.10.20.0 255.255.255.0 # internal routing ke arah # push tun-ipv6 ifconfig-ipv6 2345::1 2345::2 push "ifconfig-ipv6 2345::2 2345::1" push "route-ipv6 2002::/64" push "route-ipv6 2000::/3"
Konfigurasi Client Gateway

ip addr add 2003::1/64 dev enp0s8
TIDAK ADA Tambahan konfigurasi di client.ovpn. Pastikan setup interface BENAR. Pastikan setup routing BENAR.
