Vodafone provision like this: 200Mb/s (download) 50Mb/s (Upload) 72Mb/s (Multicast for Vodafone TV)

which is quoted all around here, but does not explain why when streaming a multicast stream, there is a drop in downstream bandwidth.

thus shooting in a barrel to try to work out how that segregation is made, assuming its not a hardware imposed drop in performance.

TimA: I thought all traffic goes through the PF Sense server???

Are you a disinformation agent? Who are you working for? And give back my Mbps!..

Ill get some Mb/s from outram and shift them to your connection.

Im a little lost on how your connection has gone.
Can you download cisco packet tracer and make a map of your network with everything in terms of the TV.

Cheers

Where do you download Cisco Packet Tracer? Isn't it locked down to Cisco students or something like thtat?

You just wait..

I'm in the middle of soldering up my little network tap doohickey.

Then I'm gonna log some stuff that I don't know how to interpret..

Then I'm gonna be back on here for more help...ok..

I'm bad at wireshark too :(.

Pondering here:

Could it be that the STB (or HG659) is applying a QoS tag, i.e. is VF over provisioning (i.e. say 300Mbps instead of 200/250Mbps or whatever it is), but set a particular tag to have say 30% of the total bandwidth, with anything untagged no more than 70% of the provisioned speed? The multicast traffic going down the non-QoS/DSCP tagged route is capping the maximum speed of general traffic.

It's just a random thought, I have no experience with Vodafone's fibre deployment..

Vodafone provision like this: 200Mb/s (download) 50Mb/s (Upload) 72Mb/s (Multicast for Vodafone TV)

Right, so if the STB via HomeHub doesn't impact the 200Mbps allocation (based on http://www.geekzone.co.nz/forums.asp?forumid=40&topicid=151247&page_no=6#1112893), I'm assuming that there a 300Mbps connection provisioned to the ONT?

Which means, does the STB apply a DSCP tag to it's packets that pfSense is stripping, or is a firewall rule in the HomeHub applying a DSCP tag to packets from the STB's static IP? OR is another method used to keep the two allocations seperate. QoS seems logical but...

I have got it working on an ASUS gateway. If you get a calculator and add it up sure it must be 323Mb/s (TOTAL) Even though the downstream and upstream are completely not of any relation to the multicast traffic.

And are you getting bandwidth drop whilst streaming as described?

No, The tests i did with this guy had no impact. If a stock standard ASUS can do it i am sure there isnt anything special.

as mentioned above, it could be a case of a tag being stripped however. in which case, the ASUS by default might be simply forwarding it on.

good news is, you should be able to bridge and listen in easily on this one.

..Or it implements the correct settings by default in related to QoS, PCP or whatever is needed?

Can you provide exactly what settings you used?

There is a thread that someone posted earlier on. for the Asus + VF TV on UFB.

Run 'tcpdump -vvvnni -w capture.pcap' on the inside interface of pfsense then copy the file off and read with wire shark.

My guess is that the hg659 is QoS transparent and passing through the pcp 4 tags, but pfsense is stripping them. (STB marks packets similar to how an ATA marks packets.

Perhaps need to get pfsense to 'trust' the markings.

(Put the interface name after the i in tcpdump)

hio77: Hows progress on this going?

I successfully created my network TAP which works on the LAN side at 100BASE-T however unsuccessfully it wont operate at 1000BASE-T (which I found out is impossible for a passive TAP) and the ONT wont seem to connect to the router at anything less than that.

My next option was gonna try this: http://www.m0rd0r.eu/how-to-make-transparent-bridge-with-slackware-linux

Will try your suggestion too Chris..
