GPON AN5506-04-F: Enabling routing in Lan port 1

Network schema

GPON port 3 connected to Indihome STB (It depends on your installation)

We are going to connect TL-TP720N Uplink to GPON Port 1 and enabling GPON Port 1.

Note: blue pencils are existing configuration, red pencil is a modification.

Save your new configuration, and your TP-TP720N is ready to act as router.

Debian Buster: configure local dns cache for Indihome user

To make your debian faster to lookup name server, it is better to use local dns cache.

Install dnsmasq
# apt-get install dnsmasq

Install NetworkManager
# apt-get install network-manager

Edit /etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifupdown,keyfile
dns=dnsmasq

Edit /etc/NetworkManager/system-connections/[your connection profile]
[ipv4]
dns=8.8.8.8;1.1.1.1;
dns-search=8.8.8.8;1.1.1.1;
method=auto

Restart your network manager
# systemctl restart network-manager

Try your local dns cache
# dig garasiku.my.id @localhost
# dig google.com @localhost

Tested on Debian 10.4
