Replacing a zyxel home router - IGMP proxy for IPTV problems

Hi,

   I am trying to replace my ISP-provided Zyxel home router with a PA-200.  I'm also subscribing to IPTV from the same ISP, with a Thomson DBI-8500E-TLN2 IPTV PVR.

The zyxel - while branded, appears to run standard zyxel firmware - the config doesn't contain anything related to IPTV, but it has an "IGMP Proxy enabled" setting.  Is there a way to set up a similar setup on the PA-200?

I'm running interface1/4 as DHCP client to the internet side - "untrust" zone (public IP), and doing NAT to interface1/3 (192.168.1.1/24).  I've been playing with the multicast settings on my virtual router, but have so far been unable to get anywhere - IGMP/multicasting is something I've never touched before.

Any pointers where I go from here?  I'm running 6.0.2, and have played a bit with packet capture, so I can see "Membership Report group" and "Leave Group" messages coming from the Thomson, but can't see any other IGMP related traffic.

Hello,

You can check couple of things:

1) From Packet capture confirm the IGMP Version used by Thomson and enable same version on Palo Alto.

2) Under Virtual Router->default->Multicast check on Enable

3) Under Interface in above settings enable IGMP on interface 1/4 and select the version as you see in step1.

Regards,

Hi,

  thanks, but so far, no luck.

Wireshark (and zyxel config) reports IGMP v2, so that's what I've been using.

Enabling IGMP on eth1/4 (or rather - creating an interface group on the vrouter) does not appear to give me anything more either.  If I add eth1/3 (internal/trust interface), I get some output from igmp statistics and memberships:

admin@gw# run show routing multicast igmp membership

The Thomson IPTV PVR is a 192.168.1.61, and its membership changes whenever I change channels.  (In the output above, it is listed twice - that is just because I changed channels rapidly, so I guess an older membership didn't time out yet).

However, I've tried doing the IGMP settings on eth1/4, eth1/3, a group with both 3 and 4, and two groups with 3 and 4 in each.  I have no idea about the other multicast settings - Rendezvous Point, PIM etc - I haven't touched anything else.

admin@gw# show network virtual-router default multicast
multicast {
  enable yes;
  interface-group {
    "IPTV IGMP" {
      pim {
        enable no;
        dr-priority 1;
        bsr-border no;
        assert-interval 177;
        hello-interval 30;
        join-prune-interval 60;
      }
      interface ethernet1/3;
      igmp {
        max-sources unlimited;
        max-groups unlimited;
        query-interval 125;
        last-member-query-interval 1;
        max-query-response-time 10;
        router-alert-policing no;
        enable yes;
        version 2;
        immediate-leave no;
        robustness 2;
      }
    }
  }
}
