I would like to use the deco m9 as main router with several additional acces points in combination with KPN Glasvezel Internet and TV. 

for so far, it seems that i have a working solution as expected :

• Normal Internet (PPPoE on VLAN 6)
• Live Television (on VLAN 4)

except one thing, that the replay function, tv guide, etc doesn't work on the KPN TV Set Top Box.

after some research it seems that you need to set some additional settings which is not accesable through the interface. So maybe it's possible to add KPN to the selection list (with the additional parameters), or add the posibility to adjust the settings through e.g. the webinterface.

the following settings are necessary to make ful advantage of the KPN tv settop box :

• IGMP proxy. (IGMPv2)
• IGMP Snooping 
• IGMP Fast leave 

i think these 3 are already activated when you set the function IPTV/VLAN because live tv is working as expected and switching between channels works flawless (i didn't measure network traffic)

The following settings need to be added to use Replay TV andTV Guide, etc :   

• DHCP Option 60 (Vendor Class Identifier) : String IPTV_RG
• Option 121 (Classless Static Route Option) [RFC3442]

Without these critical settings the DHCP server from KPN TV doesn't response and you won't receive an IPTV IP-Address. So there is no 'normal' unicast internet connection.

Please advise how to proceed, i'am happy to do testing.
