Is igmpproxy even neccessary for setting up IPTV?

[bosukes]

What does it do anyway? I got an IPTV, but it's only watchable through ISP's custom BOX thing, not on all PC's like most IPTV's. I don't know for sure if I ever need it? So simply put, does it prevent igmp packages from filling the LAN ports or something, which those packages are supposed to go the LAN port where IPTV is plugged in?

Is your IPTV multicast and IGMP subscription based?

If so you need IGMP.

Since IGMP is multicast and doesn't traverse the network, you need a proxy to operate between the upstream and downstream interfaces - hence igmpproxy.

I am not sure I understand your terms, it's too complicated. Maybe this would help here. Okay I checked on my old VDSL modem, which was asus dsl-ac68u. It was like this on tivibu IPTV, which was working setup:

Choose IPTV STB port: LAN1
USE DHCP routes: Microsoft
Enable multicast routing: Enable
Enable fast leave: Disable
Enable efficient multicast forwarding(IGMP snooping): Disable
UDP Proxy(udpxy): 0

I don't know anything else, should I enable this IGMP snooping though? It can't hurt to enable it right?

Your reply isn't really clear. Are you asking something about an issue you're having?

@bosukes

Enable efficient multicast forwarding(IGMP snooping): Disable

Your old settings didn't have IGMP snooping enabled.

You asked what igmpproxy does, then you proceed to ask if you need other settings. I cannot guess your issue, so I'll just provide a sample igmpproxy config based on your comments:

@bosukes

Choose IPTV STB port: LAN1
USE DHCP routes: Microsoft
Enable multicast routing: Enable
Enable fast leave: Disable
Enable efficient multicast forwarding(IGMP snooping): Disable
UDP Proxy(udpxy): 0

config igmpproxy
        option quickleave 0 #<--- 'Enable fast leave: Disable'
#       option verbose [0-3](none, minimal[default], more, maximum)

config phyint
        option network wan
        option zone wan
        option direction upstream
        list altnet 0.0.0.0/0

config phyint
        option network lan
        option zone lan
        option direction downstream

This should be all that's needed.

I am just trying to understand. If my IPTV company is multicased and IGMP subscription based,then enabling IGMP is good. I get that far. What if it's not? If I still enable them I will be ok? I called the company but they gave me dumb answers. They don't know anything. They just wanna sell me their routers instead Most they'll say is "we don't support that" Aren't ISP's required to give such detailed info when asked? They are purposefully not giving me detailed info to force me into buy their routers...

I'll try to enable IGMP proxy and see what happens though tomorrow.

@bosukes

What if it's not?

Your ISP can tell you how to access your TV services, it shouldn't be this big mystery.

@bosukes

If I still enable them I will be ok?

• What is "them"?
• Will you be OK with what?

To be honest, I don't understand the premise of your questions.

@bosukes

@bosukes

but it's only watchable through ISP's custom BOX thing, not on all PC's like most IPTV's.

So I'll ask this:

• Are you trying to remove your ISP-provided router and set-top TV boxes?
  • igmpproxy should allow you to remove an ISP router, if your IPTV is based on IGMP
• Where do you get the impression "most IPTVs can be watched on PC" - did your ISP provide instructions for watching TV on your PC?
  • If so, can you share that information?

@bosukes

Aren't ISP's required to give such detailed info when asked?

In FCC land (the US), technically, yes (for Internet they have to provide ability for Bring Your Own Equipment, that doesn't mean the technician on the phone has a clue of what you're referring to, also, they can refuse to provide service support/repair without their equipment installed) - but you're referring to TV service. Other countries, not so much.

[bosukes]

I just want to remove ISP provided router in the future. No need for removing their tv box, too much hassle probably.
No they don't let watching on PC. Only on their tv-box.
Well thanks for help. I actually succeeded this, but TV was kinda choppy. I was thinking maybe cuz I didn't enable igmpproxy, it was why it was like that. Or too underpowered CPU, that's why I was asking. I used ZYXEL P2812, which is 500Mhz.

Well, yes, if you eliminate the ISP router, you need to ensure your new border device can handle the [I assume HD, maybe even 4K] TV streams being "IGMP proxied" from the ISP's IPTV system in WAN - to LAN. Actually, IGMP doesn't matter, you need to be able to handle the bandwidth of those streams with enough remaining bandwidth your for Internet traffic to move smoothly while watching TV (you noticed the choppy TV).

@lleachii

also, they can refuse to provide service support/repair without their equipment installed

Another nasty trick they could employ with Bring Your Own Device (BYOD) -they could also decide not to "prorate" the bandwidth (or data limit) on your Internet service against what you use for IPTV.
