How to apply static routing (T-Mobile NL)?

[Siroy95]

Hi everyone,

I am trying to get my UDR to work with a T-Mobile Thuis (NL) DSL connection using this script.
T-mobile used to work with bridged IPTV, but for their new platform they seem to use routed IPTV (with a DSL connection).
Internet connections are made using VLAN 300, which is working fine on its own.
A DSL modem in bridge mode is used which passes all of the provided VLANs from T-Mobile.

The IPTV VLAN is 640, but also requires static routes to be set from the LAN to the TV-VLAN.
Since this is by default not possible, I thought this script could be a solution to make it work.
I am however struggling to figure out how to apply the static routes.

Running the script, selecting WAN VLAN 640, WAN range 0.0.0.0/0 (or the static routes ip's provided as WAN range), DHCP (tried various options), and a separate VLAN (99) for IPTV on the UDR.
I did get some connection working to the STB, however, the image freezes after 1 or 2 seconds of playback.
Also, when I run the script the internet connection stops working, so I must be doing something wrong.

So my question is how to apply the provided static routes from the LAN to the TV VLAN on the WAN side.
Maybe someone else managed to get IPTV working with a T-Mobile DSL connection.

I am currently unable to post the diagnose logs, but if they will help with my questions I can post them later.
