Hi there,
I've assembled little instruction that should help you with configuring your Telia IPTV.
1. Go to your VLAN configuration page Network > VLAN
2. Create a LAN network on LAN Networks tab, call it something like "IPTV".
3. Edit it. Set IP address to any available subnet, e.g 192.168.12.1.
4. Set IP netmask to 255.255.255.0. Save new lan.
5. Go back to VLAN networks tab and choose Tag based mode, add new vlan with ID 6 and choose your new lan in dropdown menu on the right. Save it.
6. Now you will have to go into your routers networks configuration file and edit it. Do it with CLI or WinSCP.
How to use CLI commands: https://wiki.teltonika-networks.com/view/UCI_command_usage
How to use WinSCP: https://wiki.teltonika-networks.com/view/How_to_upload_and_download_files_from_the_router_(Windows)%3F
7. Navigate to etc/configs/network
8. Look for config switch_vlan but following with option vid '6' line.
Should look something like this:
config switch_vlan
option device 'switch0'
option vlan '2'
option ports
option vid '6'
8.1. You will need to remove full option ports line with text editor and replace it with:
option ports '3 1t'
9. Save your file with text editor and your Telia IPTV shold be working just fine.
