IGMP Multicast and IP Passthrough on BGW700-210
I've FINALLY figured out how to put my BGW into IP Passthrough so my UDM Pro is getting the WAN IP. The only trouble now are my set top boxes - they will lose signal after only a few minutes. All 3 boxes are hardwired with an unmanaged switch at each location. I've been doing some research and googling and ran across something called IGMP Multicast and that appears to be my problem?
My network topology is as follows - AT&T RG Port 1 to WAN port on UDMP. Lan port on UDMP to Port 1 on Netgear switch. The other 3 Ethernet runs that handle IPTV are plugged directly to the UDMP. Instead, can I plug the 3 Ethernet cables to the Netgear switch to restore the TV signal? or would I need a switch between the RG and UDMP?
