IGMP- seemingly complex setup

[aug487]

Hello all,

currently have a setup like:

PC <.x–--192.168.1.x-----.1> PFsense2.0 <.2----192.168.2.x-----.1>Cisco 881 GRE+IPsec>  Internet  <remote vpn="">The GRE+IPsec work great, I'm able to telnet into servers that i need to.
The Pfsense box NAT's 192.168.1.x -> 10.245.5.192/27 as requested by the remote company for the applications.

On the Cisco router I see a PIM neighbor as the remote GRE tunnel endpoint, and join-group statements are configured on the router which seems to be working.

The issue seems to be in the PFsense box.

Does anyone have any insight how i can join multicast groups ( ip's 233.111.180.96/27  233.111.180.128/27 ) from the 192.168.1.x network.

I've followed some advice for setting up igmp proxy,  but it seems the igmp packets still are passing thru the router. ( i have configured the firewall/advanced options)

Thanks in advance</remote>
