Multicast traffic through the ERLite-3 router.

The router has been updated with the EdgeRouter Lite v1.6.0 version and is configured for WAN+2LAN with the wizard. There are three networks with the following settings:

  1. WAN - dhcp client (getting public address from ISP)
  2. LAN1 - 192.168.1.0/24
  3. LAN2 - 192.168.2.0/24

I have not been able to get the multicast traffic working between the networks. Is it possible to configure the router to “pass through” multicast traffic (239.10.10.10) between the different networks in some way?

Re: Multicast traffic through the ERLite-3 router.

Thanks!

After several of hours of testing different multicast configurations the multicast traffic through the router finally works :-)

I did the following steps:

1) Configure your equipment (Linux for me) to accept multicast:

> route -n add -net 224.0.0.0 netmask 240.0.0.0 dev eth0

2) Configure your equipment with a default gateway:

> route add default gw 192.168.1.1

3) Set up an IGMP-Proxy according to:

4) Use a multicast application that can send multicast packets with a TTL (Time-To-Live) larger than the limit used in the IGMP-proxy configured in the router.

 

Use wireshark or similar software to examine/verify your network traffic.

 

Good Luck !

Re: Multicast traffic through the ERLite-3 router.

Some multicast applications may work with "igmpproxy" set up. You could find some more information/example in the KB and previous forum discussions (e.g., here and here).
