is anyone using his openbsd pf box as a replacement for the standard t-com router? the only reference i found was from the linux community (sorry, german only: http://claus.freakempire.de/2007/04/15/t-home-iptv-ohne-speedport-unt...). their how-toīs say, that one has to use vlan id 7 on the dsl-modem-side ethernet card. that should not be too hard i guess. on top of that pppoe is used. should work, too.
the only thing i am not quite familiar with is the use of multicast routing/igmp to get the bundled ip-tv receiver working. the linux guys use igmp-proxy for that to work. i could not find any igmp proxy for openbsd so far. can pf or mrouted handle multicast/igmp forwarding to the private ip address space (192.168.x.x) i use behind nat?

many thanks again for sharing the proxy! i finally got vdsl and hacked together a small howto as i could only find linux specific ones. http://un.geeig.net/openbsd-vdsl.html suggestions, comments, corrections, more elegant ways are always welcome.
2 questions come into mind: - Does the new IP-only (w/o IPTV) offer (started in Sep-2009 by German Telekom) still requires the vlan setup? - How does the vlan setup interferes with a carp/pfsync configuration?

Assuming the same technical infrastructure is used for that offer: yes. I have always found the guys at the onlinekosten.de forum to be very helpful, maybe you can ask there to know for sure.

Never tried that.
Anyway the HowTo is outdated and does not work anymore for IPTV. Vlan8 is used for Multicast now and the required IGMP version is v3 there. OpenBSD does not support IGMP v3, so I'm stuck with a Linux Router for Vlan8 right now. Vlan7 is still connected to my beloved OpenBSD Box, though ;)
Yes I had but there was no IGMP Proxy functionality. It was on the TODO list though.

It just does Multicast Routing / IGMP proxying, announces the few nets that have to be routed via Vlan8 dynamically and firewalls itself with user unfriendly IPTables ;)
On a sidenote, I would order the cheapest IPTV VDSL offer. The others have a bandwith limit once you exceed a certain threshold. Have a look at the AGB.
