EX3301-T0 Being Bombarded by IGMPPROXYv3 Messages

Griswold

I am seeing the following multiple times every second in my System Log

igmpproxyv3: IGMPv3-Proxy: Received I/F msg from OS

igmpproxyv3: Get MTU is NULL, set 1500 as default if_name=[ra0]

I've raised this with my ISP but to-date they haven't got back to me.

The log is filling up and overwriting in minutes as there are around 20 of these every second.

Can anyone suggest where these are likely coming from and what I can do about them?

Many thanks in advance.

Griswold

Thanks again Peter

I've disabled igmpproxy in Broadband Settings, so thanks for that suggestion. Those log messages have now stopped.

Multicast Forwarding is ON in WLAN settings but greyed out so can't be changed.

You can try to deactivate IGMP proxy in your broadband section if your firmware let you do so . Must be Etrhernet PPoE connection .

Normal way you dont need this IGMP proxy .

Griswold

Thank you Peter and yes, it looks like it's coming from or via my ISP using the PPPoE connection. I have temporarily turned IGMPproxy off on the router until I hear from my ISP. If has certainly stopped the log being flooded but I don't know if anything on my network actually needs it.

It was certainly ON and causing no issues before my ISP made some changes at their end in moving my what was a static ip address to a new address behind their firewall. The original one was not behind a firewall at their end.

I will update this as soon as I hear from them

Many thanks again for your help.

No, i think you should stop trying to connect to that proxy , this is only for multicast service for TV .

In the Wlan setting there is an option "Multicast Forwarding" if you think that there are problems

with multicast this transforms all packages in unicast .

But - The Router shows Informations to you which stresses you . Too many options present .
