Transparent bridge problem
-
Why not put in an inexpensive switch? Plug in the cable modem, STB, and WAN. Done.

why not just plug your settop box directly into your modem?

why not just plug your settop box directly into your modem?
Which would also work, provided it has multiple LAN ports. For some reason, I had it in my head that your modem only had one LAN interface.

hey called it a
"The ISP modem is also a router (modem/router/switch/AP … all in one)"Sure would think it would have more than 1 lan side interface.

I'm glad one of us can read… ;)

So for example some of the business routers you can get from isp, so port 1 gives the device connected to it public, and then 2 thru 4 are natted. I have never seen a isp device that could give you mixed IPs in how he has it setup.
It would for sure require vlans to do something like that..
He seems to show that his isp device is on rfc1918 on port, and at the same time he wants to get a public IP? Why sure you can do that with a subinterface, etc. there would be a vlan tag on it, etc.

Hi
The 'ISP cable modem/router' (EuroDocsis 3.0) is indeed a 'all-in-one' with a build-in switch with 4 LAN ports. I use only 1 LAN port and that is connected to igb0 on my pfSense.
This ISP modem/router gives directly connected devices a private IP, but their own directly connected settopbox is getting a public IP - I guess they recognise the MAC address of that box, I don't know if they work with VLAN tags. The settopbox realy requires a public IP, otherwise (if it gets a private address) eg. you can't see the TV guide schedule for the upcoming week or you can't manage your programmed recordings and it doesn't get software updates.Like johnpoz says, yes I can connect the settopbox directly to a other LAN port of the ISP modem/router, but I would like to do it via my pfSense box so that I don't have to pull a extra cable from my TV to the basement. An of course just because it should work :-)
On the ISP modem/router, there are only 4 LAN ports available. It doesn't matter wich one you use for which device. On all ports you get a rfc1918 address, but if you connect the settopbox, it gets a public address.
So I was trying to setup a bridge from the settopbox to the WAN port of pfSense that is connected to one of the LAN ports of the ISP modem/router to get a public IP.

Pretty sure it uses some VLAN for TV. Complete waste of time in that case.
-
I bet it works with MAC passthrough, how should it recognize the settopbox otherwise to give it a public IP?
-
Run a cable, and directly connect it.. Or use a switch in front of pfsense if you don't want to run 2 wires. I would run 2 wires ;)
Or you can sniff the traffic from your set top box and see exactly what is going on, could be something with dhcp option and jumping vlans like a phone can do, etc. But without understanding how its getting the public how do you expect to make it work behind pfsense?
