Question

Forticlient casuing an igmpv2 storm on my student vlan

I recently have uninstalled forticlient from an imaged machine, in an unrelated matter, and in putting the client back on the machine, I simply used the offline installer.  after registering and firing this up, I notice aan IGMPv2 storm across my student vlan where the machine is connected to.  when I turn forticlient off or disconnect the laptop I have just connected this stops.  I'm wondering if anyone can shed some light on this?

 

thanks

    What group was it being sent at and are you 100% sure it's the client? Don't know how vpnclient would use igmp much less send to a igmp group.

     

    Was the host inspected?

    when I connect the forticlient the storm starts....when I disconnect or unregister the client it stops...im seeing it via wireshark, so that would tell me that it would have something to do with forticlient.  just an educated guess....

    If it works, then the cause was application firewall.

    Hi - what version of the client were you using? We've seen a similar issue (on a corporate network) with version 5.2.5.0658.

     

    This forum entry https://forum.fortinet.com/tm.aspx?m=131412 appears to indicate this is an issue with the application firewall element of the client.
