multicast on cisco 3750 and cisco rv180 - only receiving unicast

I've been struggling with multicast for some bit now. I receive video through unicast.

The following is true:

A 3750 is configured as such:
interface GigabitEthernet1/0/11
description Uplink to CiscoRV180
no switchport
ip flow ingress
ip flow egress
ip address 172.27.255.33 255.255.255.252
ip pim sparse-mode
ip igmp query-interval 125
flowcontrol receive desired
spanning-tree portfast disable
spanning-tree bpdufilter disable
spanning-tree bpduguard disable
end

ip pim rp-address 10.10.254.32
no ip pim dm-fallback
ip mroute 172.27.91.192 255.255.255.240 172.27.255.23
ip route 172.27.91.192 255.255.255.240 GigabitEthernet1/0/11 172.27.255.34

connected to WAN port on the RV180 switch:

WAN Information-
IP Address: 172.27.255.34
Subnet Mask: 255.255.255.252
Gateway: 172.27.255.33

Routing Mode: Gateway (NAT)

Access Rules:
Default Outbound: Allow

One-to-One NAT
Private Range: 192.168.2.151
Public Range: 172.27.91.193- 196
Service: ANY

IGMP Proxy: Enable
Upstream: WAN
Allowed Networks: 192.168.2.151 - 154 Length - 32

I can see the video in unicast but can't see it in multicast. Do I have the routes right?

multicast debug is on. I see no traffic concerning 172.27.91.x.

Have you configured PIM on the VLAN where the multicast source resides?

mikebernhardt

Als oyou have to configure multicast globally with "ip multicast-routing "

Yes to both. Multicast is working for other switches and subnets on the same switch but not this particular one. It's going to an RV180 connected to the WAN port from the switch that is receiving multicast from other devices on the same switch. The RV180 has multicast within its LAN but outside the WAN it isn't passing through. One to one nat is setup for that RV180.

Craig Beck

Can you turn NAT off on the RV180?

ASKER

I don't think so because the network on the WAN side of the network has a 172.27.x.x address. The network on the LAN side has network address in 192.168.2.x. If I turn off One to One NAT both networks wouldn't be able to even see each other; let alone pass multicast.

None of the solutions worked. Had to take Router out of the mix for broadcast to work.
