IGMP Proxy unable to Select GRE as Interface

[ben987654321]

Hi,

A very simple question, I hope someone can give quick answer.

I have a working GRE Tunnel and Interface added but I can't select that tunnel as the upstream or downstream interface for IGMP Proxy because the interface just isn't listed in the drop down menu of the IGMP Proxy page.

All the documentation and forum posts I've seen seem to indicate I should easily be able to choose the GRE Tunnel interface in the IGMP Proxy config.

Can someone confirm for me that I should be able to and if not explain to me how I can get IGMP Proxy/multicast over my GRE Tunnel.

Thanks!
