This repo contains the files you need to succesfully configure the USG with KPN FTTH with IPTV and IPv6 enabled.

Place config.gateway.json at the unifi controller (sites/default) via SCP
The config.gateway.json contains the main configuration with the different interfaces which are needed for internet (vlan 6) and IPTV (vlan 4). IPv4 is configured via PPPoE with the kpn/kpn username and password. KPN uses a TAG which is configured in the DSLAM to identify your connection and to give you your "permanent" public IPv4 address.
-
Place kpn.sh in /config/scripts/post-config.d/ via SCP
-
Execute
chmod +x /config/scripts/post-config.d/kpn.shon the USGAfter each firmware upgrade the routes file, used by the dhcp client at the exit hook (for the IPTV routes), is removed. To overcome this, after each upgrade the USG will execute this script which will create the routes file, renews the DHCP lease, restart the IGMP Proxy.
KPN sends static routes via DHCP which the USG does not install by default. This script will install the DHCP routes when a DHCP lease is received. The chmod +x command allows the script to be executed. (source)
-
The lan network (and portfowarding if needed) needs to be configured in the Unifi controller
-
Go to the USG in devices in the controller and force provisioning
After provisioning please reboot the USG. After two minutes IPv6 will be enabled. This can be checked by executing show interfaces on the USG. If IPTV does not work, please restart the USG again.
The PPPOE interface has no "public" IPv6 address because it uses the link local IPv6 address to route traffic to KPN. To see the remote address execute the following command (source):
show interfaces pppoe pppoe2 log | match "IPV6|LL"
If you are using VLANs and have issues with the IPTV having hickups or being frozen you can try to change the config as follows:
At the "igmp-proxy" section replace "eth1" with "eth.{vlan}" where {vlan} would be the VLAN where your decoders are in.
"eth1.100": {
"alt-subnet": [
"0.0.0.0/0"
],
"role": "downstream",
"threshold": "1"
}
To prevent the IPTV from flooding other network interfaces it's best to explicitly disable the proxy for these interfaces:
"eth1": {
"role": "disabled",
"threshold": "1"
},
"eth1.200": {
"role": "disabled",
"threshold": "1"
},
"eth1.300": {
"role": "disabled",
"threshold": "1"
}

This config.gateway.json has been tested on the following versions:
UniFi Security Gateway 3P: 4.4.51.5287926
Unifi Controller: 6.0.23 (atag_6.0.23_14253)
My Unifi WAN settings in the controller are as follows:
